AD7686CRMZ

Analog Devices · Analog To Digital Converters (ADC) · MSOP-10

AD7686CRMZ from Analog Devices, in a MSOP-10. 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 input Reference input voltage with a range from 0.5 V to VDD, referred to GND, and to be decoupled closely with a 10 µF capacitor.
2 VDD power_in Power supply pin, specified for operation from 4.5 V to 5.5 V in the Specifications table.
3 IN+ input Analog input referred to IN−, with a differential voltage range of 0 V to VREF.
4 IN− input Analog input ground sense, connected to the analog ground plane or to a remote sense ground.
5 GND power_in Power supply ground pin.
6 CNV input Convert input that initiates conversions on its leading edge, selects chain or CS interface mode, and enables SDO in CS mode when low.
7 SDO output Serial data output carrying the conversion result, synchronized to SCK.
8 SCK input Serial data clock input that shifts the conversion result out when the part is selected.
9 SDI input Serial data input that selects the interface mode: low at the CNV rising edge selects chain mode and high selects CS mode.
10 VIO power_in Input/output interface digital power, nominally at the host interface supply of 1.8 V, 2.5 V, 3 V, or 5 V.
