Typical Applications
LTC6363HMS8-2#PBF is suitable for 6 applications: SAR ADC Driver, Industrial Process Control, Medical Instrumentation, Communication Systems, Data Acquisition Systems, Battery-Powered Instruments.
SAR ADC Driver
The LTC6363HMS8-2#PBF is optimized to drive SAR ADCs, providing a differential signal with low noise and high bandwidth. Its fixed gain of 2V/V simplifies the signal chain, and its rail-to-rail outputs maximize the ADC's dynamic range. The low power consumption makes it suitable for portable instruments. With a 35 MHz bandwidth and 75V/Β΅s slew rate, it can drive high-speed SAR ADCs without settling issues. The VOCM pin allows precise setting of the output common-mode voltage to match the ADC reference, ensuring optimal performance.
Recommended
Industrial Process Control
In industrial process control, the LTC6363HMS8-2#PBF conditions sensor signals before digitization. Its precision (50Β΅V offset, 100dB CMRR) ensures accurate measurement of temperature, pressure, and flow. The wide supply range (up to 11V) allows operation from 24V industrial rails with proper regulation. The -40Β°C to 125Β°C temperature range ensures reliability in harsh environments. The fixed gain of 2V/V reduces component count and improves system reliability.
Recommended
Medical Instrumentation
The LTC6363HMS8-2#PBF is used in medical devices such as patient monitors and diagnostic equipment. Its low power (1.1mA) is critical for battery-powered devices. The high CMRR rejects common-mode interference from the human body, and the low noise ensures accurate biopotential measurements. The small 8-MSOP package fits compact designs. The fixed gain simplifies calibration, and the rail-to-rail outputs interface directly with ADCs in the signal chain.
Recommended
Communication Systems
In communication systems, the LTC6363HMS8-2#PBF conditions IF or baseband signals before ADC conversion. Its 35 MHz bandwidth supports wideband signals, and the high slew rate preserves signal integrity. The differential output reduces even-order harmonics and improves SNR. The low power is beneficial in multi-channel systems. The fixed gain of 2V/V is useful for standardizing signal levels across channels.
Recommended
Data Acquisition Systems
The LTC6363HMS8-2#PBF is a key component in data acquisition systems, providing signal conditioning for various sensors. Its precision and low noise ensure accurate digitization. The wide bandwidth allows it to handle fast transients, and the rail-to-rail outputs maximize ADC range. The shutdown pin enables power saving in duty-cycled systems. The fixed gain simplifies system design and reduces calibration effort.
Recommended
Battery-Powered Instruments
The LTC6363HMS8-2#PBF is ideal for battery-powered instruments due to its low supply current of 1.1mA. It operates from a single 2.8V supply, making it compatible with Li-ion batteries. The shutdown pin further reduces power consumption to microamps when idle. The small package and minimal external components (no gain-setting resistors) save board space and extend battery life. The precision specifications ensure accurate measurements in portable devices.

Key Differentiators
- Fixed gain of 2V/V with internal matched resistors (vs LTC6363HMS8#PBF)
- Lower input bias current (100 nA) (vs THS4551)
- Higher DC CMRR (100 dB) (vs THS4551)
Design Notes
Ensure proper power supply decoupling. Place a 0.1Β΅F ceramic capacitor and a 10Β΅F tantalum capacitor close to the V+ and V- pins. The LTC6363 operates from 2.8V to 11V single supply or Β±1.4V to Β±5.5V dual supply. For best performance, keep the supply voltage stable and free of ripple.
For optimal noise performance, use a solid ground plane and keep the input and output traces short. The VOCM pin should be bypassed with a 0.1Β΅F capacitor to ground to set the output common-mode voltage. The SHDN pin can be tied to V+ if shutdown is not used.
Do not exceed the absolute maximum supply voltage of 12V. The input common-mode range is limited; ensure the input signals stay within the specified range. When driving SAR ADCs, match the VOCM voltage to the ADC reference to avoid clipping. Also, consider the settling time of the amplifier when selecting the ADC sampling rate.
