AD4698BCBZ-RL7

Analog To Digital Converters (ADC) Overview

The AD4698BCBZ-RL7 is an 8-channel, 16-bit successive approximation register (SAR) analog-to-digital converter operating at a sampling rate of 1 MSPS. It features Easy Drive capabilities that relax analog front-end drive requirements and includes overvoltage protection clamps on each input. The device supports unipolar and pseudobipolar input modes with a typical SINAD of 93 dB at 1 kHz. It utilizes a 36-lead WLCSP package and operates from a single analog supply of 2.7 V to 5.5 V with an internal LDO, or 1.71 V to 1.89 V digital logic.

Analog To Digital Converters (ADC) Feature Summary

• True 16-bit resolution with no missing codes and ±1 LSB maximum INL

• On-chip oversampling, decimation, and customizable channel sequencer
• Autocycle mode for autonomous conversions with threshold detection alerts

Analog To Digital Converters (ADC) Applications

• Photodiode monitoring
• Medical instrumentation
• Vital signs monitoring
• Electronic test and measurement
• Automated test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 corresponds to reel packaging when sourcing components. Confirm the BCBZ designation matches the required 36-lead WLCSP package variant. Ensure compatibility with the intended host system's SPI interface voltage levels before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the AD4697 if a 1 MSPS sampling rate is required. The WLCSP package provides an internal reference buffer not available in the LFCSP version. Verify that the application benefits from the relaxed AFE drive requirements provided by the Easy Drive feature set.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD4697/AD4698 family of multiplexed SAR ADCs. It shares architectural similarities with the AD4697 but offers double the sampling speed. The family is designed for space-constrained, multi-channel precision data acquisition systems requiring low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The AD4697BCBZ-RL7 is a compatible alternative within the same package offering lower performance specifications. Other members of the AD469x family may require pinout or software configuration adjustments.
