Typical Applications
AD4697BCPZ is suitable for 6 applications: Industrial Process Control, Battery Management System (BMS) Monitoring, Medical Instrumentation, Power Line Monitoring, Test and Measurement / Data Acquisition, IoT-Enabled Smart Sensor Nodes.
Industrial Process Control
AD4697BCPZ excels in industrial process control where multiple analog sensors must be digitized with 16-bit precision. Its 8-channel multiplexed input lets one converter monitor eight separate 4-20 mA loops or voltage outputs, while the Easy Drive high-Z input mode reduces burden on sensor amplifiers and eliminates external ADC drivers. At 500 kSPS/1 MSPS throughput, it can scan all eight channels rapidly for control-loop updates. Place a REF192ESZ voltage reference and ADA4522-2ARZ signal conditioning ahead of the ADC to maintain accuracy. Compared to discrete single-channel ADCs, this device increases channel density and simplifies BOM.

Battery Management System (BMS) Monitoring
AD4697BCPZ suits battery management systems (BMS) that monitor cell voltages and temperatures across a stack. Its 8 channels can be configured for single-ended cell-voltage taps and thermistor temperature readings; 16-bit resolution gives fine voltage granularity. The high-Z reference input accepts a stable precision reference such as REF192ESZ, while the multiplexed SAR architecture ensures low latency compared to delta-sigma converters. With 500 kSPS/1 MSPS throughput, the ADC can scan the complete pack quickly. The LFCSP-24 package is compact for space-constrained BMS boards. Use isolation and filtering per the AD4697 datasheet for noisy automotive environments.

Medical Instrumentation
AD4697BCPZ's 16-bit resolution and Easy Drive inputs make it well suited to medical instrumentation such as patient monitors, ECG and blood pressure modules. The high-Z input mode preserves signal integrity from high-impedance sensors without requiring a dedicated ADC driver, which lowers power and noise in portable devices. Its 8-channel multiplexer can sample multiple physiological signals in sequence; 500 kSPS/1 MSPS throughput easily captures ECG bandwidths of a few hundred hertz. The small 24-LFCSP package fits compact medical PCBs. Pair with a low-noise REF192ESZ reference and ADA4522-2ARZ amplifier for best performance. Compliance with medical safety standards must be verified in the end system.

Power Line Monitoring
In power quality monitoring and energy metering, AD4697BCPZ digitizes voltage and current waveforms from instrument transformers. The 8-channel multiplexer can connect to three-phase voltages and neutral currents, while 16-bit resolution captures harmonic content down to small amplitudes. Easy Drive high-Z inputs allow the ADC to be driven through simple resistive dividers without a high-speed op amp, and the high-Z reference input permits a precision reference like REF192ESZ. With 500 kSPS/1 MSPS sampling, the device resolves 50/60 Hz fundamentals and harmonics with ample oversampling. The LFCSP-24 package is suitable for compact metering modules.

Test and Measurement / Data Acquisition
For benchtop multimeters, data acquisition (DAQ) modules, and ATE systems, AD4697BCPZ delivers 16-bit, 8-channel multiplexed conversion in a compact LFCSP-24 package. Its 500 kSPS/1 MSPS throughput supports scanning multiple inputs with good update rates. The Easy Drive feature simplifies front-end design: high-Z inputs eliminate the need for buffer amplifiers, reducing cost and PC board area. The device is compatible with standard serial control signals and requires an external precision reference. Use a low-noise REF192ESZ reference and remember to decouple the LFCSP-24 supply pins with 0.1 uF and 10 uF capacitors. This ADC is an excellent drop-in for multi-channel precision measurements.

IoT-Enabled Smart Sensor Nodes
In IoT-enabled sensor nodes and smart factory systems, AD4697BCPZ acts as a precision 16-bit conversion engine for multiple analog sensors. The 8 channels read pressure, temperature, and strain gauges, while Easy Drive high-Z inputs allow direct connection to many sensors without complex driver circuits. Low per-channel cost and a small LFCSP-24 footprint enable high-density designs. Its 500 kSPS/1 MSPS mode supports burst sampling triggered by a microcontroller, then the node sleeps for low-power operation. Pair with REF192ESZ for a stable voltage reference and ADA4522-2ARZ for any required signal scaling. This configuration saves board space and power compared to discrete ADC front ends.

Key Differentiators
- Easy Drive high-Z inputs simplify analog front end (vs AD7091R-8BRUZ)
- Higher throughput option (vs AD4696BCPZ)
- 16-bit vs 12-bit resolution (vs AD7091R-8BRUZ)
Design Notes
Use a solid ground plane under the 24-lead LFCSP (4x4 mm) and connect the exposed pad directly to ground. Place 0.1 uF and 10 uF decoupling capacitors as close as possible to the supply pins. Keep analog inputs away from digital traces to avoid coupling; if possible route them on opposite sides of the PCB. Refer to the AD4697 data sheet recommended layout for the LFCSP package.
The AD4697 Easy Drive high-Z input mode permits high impedance sources, but the source impedance must be considered with acquisition time. For multiplexed scanning, allow adequate settling after channel switch. Use a low-leakage input filter and a precise external reference; the high-Z reference input still benefits from a 0.1 uF reference decoupling capacitor. Larger source resistances reduce achievable throughput, so balance input filtering with conversion rate.
Do not operate the AD4697 outside its [DATA_NEEDED: supply/voltage/temperature] limits. Because the device multiplexes 8 channels, confirm that previous channel residue settles before sampling to avoid cross-channel crosstalk. For applications requiring the internal reference buffer option, note that the WLCSP variant includes it; the LFCSP-24 package must use an external reference. Always pull unused inputs to a known potential to prevent floating-channel errors.
