THS4062ID Overview
A voltage-feedback amplifier (VFA) is an operational amplifier in which the feedback network sets a well-defined closed-loop gain that is largely independent of process variation. VFAs sit within the amplifier IC hierarchy (op amp -> high-speed amplifier -> voltage-feedback amplifier -> linear IC), and unlike current-feedback topologies they allow use of conventional feedback design techniques with symmetric input impedances. Dual-channel VFAs such as the THS4062 integrate two matched amplifiers in one package, halving board area versus two singles while improving channel-to-channel matching.
Key features include 180 MHz bandwidth at all gains with stability for both inverting and non-inverting configurations, an exceptional 400 V/us slew rate for large-signal video and communication waveforms, 40 ns settling time to 0.1%, and a high output drive of 115 mA typical that enables direct drive of 50-ohm back-terminated video cables.
Video performance is a defining strength: 75 MHz 0.1 dB gain-flatness bandwidth, 0.02% differential gain and 0.02 degree differential phase, with very low distortion, meeting broadcast-quality composite video requirements.
The supply range spans 4.5 V to 16 V (single or dual supplies), covering 5 V, +/-5 V and +/-12 V/+/-15 V rails. Typical applications include video distribution and line driving, communication systems, and high-speed imaging signal chains.
Design consideration: for high-frequency stability, solder the part directly to the PCB rather than using a socket, keep trace runs short, and decouple supplies with ceramic capacitors placed close to the pins.

Typical Applications
THS4062ID is suitable for 6 applications: Video Distribution and Line Driving, Communication Systems, High-Speed Imaging Signal Chains, ADC Driver Circuits, Test and Measurement Instrumentation, Active Filters and Wideband Gain Blocks.
Video Distribution and Line Driving
The THS4062ID is optimized for broadcast-quality video distribution, with 0.02% differential gain and 0.02 degree differential phase errors and a 75 MHz 0.1 dB gain-flatness bandwidth per the Texas Instruments datasheet. Each of the two channels provides 115 mA typical output drive, enough to directly drive back-terminated 50-ohm coaxial or 75-ohm video cables without an external buffer stage, reducing BOM cost and board area. In a typical distribution amplifier, one THS4062ID channel per output is configured at a fixed gain (commonly +2 V/V to compensate for cable termination loss), with a gain-setting resistor network sized for flat response. The dual-channel integration improves channel matching between outputs. Designers should account for obsolescence by qualifying the THS4062CDR drop-in substitute in new video layouts.

Communication Systems
In communication system intermediate-frequency and baseband chains, the THS4062ID's 180 MHz bandwidth and 400 V/us slew rate support wideband modulation formats without slew-induced distortion. The Texas Instruments datasheet lists communications among the primary applications for the THS4061/4062 family, citing very good AC performance and very low distortion. The 40 ns settling time to 0.1% allows the amplifier to drive sampling switches or ADC inputs in data-converter front ends with minimal settling guard time, improving channel throughput. The 4.5 V to 16 V supply range accommodates both 5 V single-supply and +/-5 V or +/-12 V dual-supply system architectures common in telecom and test equipment. When substituting, note that the TI-recommended OPA2811 has only about one quarter of the slew rate and may limit large-signal performance.
Recommended
High-Speed Imaging Signal Chains
High-speed imaging systems - including CCD/CMOS sensor output conditioning and pulsed light-detector front ends - benefit from the THS4062ID's 40 ns settling time and 180 MHz bandwidth, which let amplifier outputs settle between pixel clock phases at multi-MHz pixel rates. The Texas Instruments datasheet explicitly names imaging as a target application for the THS4061/4062 family. The dual amplifier in one 8-SOIC package enables a two-channel imaging path (for example, signal and reference or dual-slope integration paths) with tight channel-to-channel matching from shared die geometry and thermal environment. The 400 V/us slew rate handles the fast steps produced by correlated double sampling circuits. Compact SOIC-8 placement with short traces and solid ground plane is essential to preserve settling accuracy at speed.
Recommended
ADC Driver Circuits
The THS4062ID serves as a driver for medium- and high-speed analog-to-digital converters where fast settling between conversion samples is required. Its 40 ns settling time to 0.1% and 180 MHz small-signal bandwidth support ADC sampling rates in the tens of Msps range, while the 115 mA output drive comfortably charges typical ADC input sampling capacitors through a series resistor. The Texas Instruments datasheet groups the family under high-speed voltage-feedback amplifiers suited to data acquisition. Designers should size the series isolation resistor (typically 25-100 ohms) with the ADC input capacitance to damp charge kickback, and verify THD at the target input frequency since distortion figures depend on gain and load. Supply flexibility from 4.5 V to 16 V eases integration with 5 V ADC rails.
Recommended
Test and Measurement Instrumentation
Bench and rack instrumentation - oscilloscope front ends, signal generators, and automated test equipment - requires amplifiers whose gain accuracy and bandwidth remain stable across inverting and non-inverting configurations, which the THS4062ID guarantees per the Texas Instruments datasheet (stable at all gains). The 400 V/us slew rate preserves edge fidelity when driving full-scale test waveforms, and the 115 mA drive supports 50-ohm back-terminated outputs directly. Wide 4.5 V to 16 V operation permits +/-12 V or +/-15 V supplies for signal paths that must accommodate large input swings. Because the part is entering obsolescence, test-equipment manufacturers should validate the THS4062CDR as a same-specification substitute early in the design cycle to secure long-term serviceability of instrument modules.
Recommended
Active Filters and Wideband Gain Blocks
The THS4062ID is stable at all gains for both inverting and non-inverting topologies, making it a strong candidate for active filter stages (multiple-feedback, Sallen-Key) operating at several tens of MHz, where many high-speed amplifiers become unstable at low gains. The 180 MHz bandwidth yields usable Q at cutoff frequencies well into the tens of MHz, and low distortion preserves filter stopband performance. Using the dual amplifier allows a second-order section (two op amps) or cascaded gain-and-filter blocks in one SOIC-8 footprint. Per the Texas Instruments datasheet layout guidance, avoid IC sockets and minimize trace inductance, since socket lead inductance commonly causes stability problems at these frequencies; compact surface-mount placement is the best implementation.

Design Notes
Per the Texas Instruments THS4062 datasheet layout guidance, do not use IC sockets: additional lead inductance in socket pins often leads to stability problems at 180 MHz operation. Solder the SOIC-8 directly to the PCB, keep trace runs short, and place components compactly to minimize stray series inductance. Use a solid ground plane and route feedback traces directly with minimal length. These practices are the difference between achieving and failing to achieve the datasheet video performance.
Decouple V+ (pin 8) and V- (pin 4) each with a 0.1 uF ceramic capacitor placed within a few millimeters of the pins, plus bulk capacitance (4.7-10 uF) per supply rail. At 115 mA output drive per channel and 180 MHz bandwidth, supply transients are fast; inadequate high-frequency decoupling shows up as high-frequency oscillation and degraded differential gain/phase in video circuits. Keep the decoupling loop inductance low with short, wide traces to the ground plane.
The TI web replacement tool recommends the OPA2811DR for THS4062 obsolescence, but per TI E2E forum discussions (February 2026) that part has only about one quarter of the 400 V/us slew rate. Substituting it in slew-limited designs (video line driving, fast pulses) introduces large-signal distortion even though small-signal bandwidth appears adequate. Qualify the THS4062CDR instead, verifying your ambient temperature fits the commercial grade range before releasing the change.
