Product details

16-bit SAR ADC in a compact 8-MSOP

The AD7684BRMZ is a 16-bit SAR ADC from the PulSAR® series. It samples a single differential input at 100k samples per second via an SPI/DSP interface.

SAR architecture — deterministic, no pipeline

The SAR conversion core produces one 16-bit result per conversion request with no pipeline delay. That matters for multiplexed front-ends or single-shot acquisition where every sample must correspond to a known instant in time. The 1:1 S/H-to-ADC ratio means the sample-and-hold acquires the input voltage once per conversion cycle, then the SAR engine resolves bits sequentially.

Active lifecycle, no end-of-life concern

The AD7684BRMZ carries an Active product status and ROHS3 compliance.

Frequently asked questions

Is AD7684BRMZ compatible with 3.3V SPI?

Yes. With VDD set to 3.3V, the digital interface levels are 3.3V-compatible, matching standard 3.3V SPI and DSP controllers without external level translation.

When sourcing AD7684BRMZ, what is the closest functional alternative — AD7683BRMZ?

The AD7683BRMZ is a 16-bit PulSAR ADC in the same 8-MSOP package and 100kSPS sampling rate, but its input is pseudo-differential rather than true differential. The AD7684BRMZ's true differential input provides better common-mode rejection for applications where the signal and reference share a common-mode voltage. For single-ended or pseudo-differential signals the AD7683BRMZ may fit, but the input architecture difference affects the front-end design.
