AD7694BRMZ

Analog Devices · Analog To Digital Converters (ADCs) · MSOP-8

AD7694BRMZ from Analog Devices, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF passive Reference input voltage range is 1 V to VDD, referred to GND, and the pin should be decoupled closely with a ceramic capacitor of a few µF.
2 IN+ passive Analog input referred to IN−, where the differential input voltage (IN+ minus IN−) spans 0 V to VREF.
3 IN− passive Analog input ground sense, to be connected to the analog ground plane or to a remote sense ground.
4 GND power_in Power supply ground.
5 CNV input Convert input whose leading edge initiates a conversion and which enables the SDO pin when low.
6 SDO output Serial data output on which the conversion result is presented, synchronized to SCK.
7 SCK input Serial data clock input which, while CNV is low, shifts the conversion result out on SDO.
8 VDD power_in Power supply, specified from 2.7 V to 5.25 V with respect to GND.
