It is designed to drive high-performance ADCs, providing the differential signal conditioning needed between a sensor or front-end and the converter input. The dual-channel configuration saves board area compared to using two single drivers, and the 24-lead exposed-pad package helps with thermal management when both channels are running at full output. ## Package and mounting The 24-LFCSP (4x4) is a fine-pitch, exposed-pad QFN-style package. It is surface-mount only — no socket option. For a field swap, you will need a hot-air station and a stencil or preform for the thermal pad solder paste. Orientation is marked by pin 1 indicator on the top, but the package is symmetrical enough that a rotated placement is possible — check the silkscreen dot before reflow.","metaTitle":"ADA4940-2ACPZ-R7 ADC Driver, 2 Circuit, 24-LFCSP","metaDescription":"ADI ADA4940-2ACPZ-R7 dual ADC driver in 24-LFCSP (4x4).

The dual version saves board space and per-channel cost when two ADC driver channels are needed, but shares the same 24-LFCSP footprint as the single in a different pinout — they are not pin-compatible."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADA4940-2ACPZ-R7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADA4940-2ACPZ-R7 when reusing this data.
