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.","metaTitle":"AD7684BRMZ 16-Bit SAR ADC, 100kSPS, 8-MSOP","metaDescription":"ADI AD7684BRMZ 16-bit SAR ADC, 100k samples/sec, differential input, SPI/DSP interface, 2.7V-5.5V supply, -40°C to 85°C.

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."},{"question":"When sourcing AD7684BRMZ, what is the closest functional alternative — AD7683BRMZ?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/AD7684BRMZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/AD7684BRMZ when reusing this data.
