Texas Instruments · Analog To Digital Converters (ADCs) · VSSOP-10-0.5mm

ADS8865IDGS from Texas Instruments, in a VSSOP-10-0.5mm. 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	Positive reference input that must be decoupled with a 10-μF or larger capacitor; the reference operates from 2.5 V to 5 V independent of AVDD.
2	AVDD	power_in	Analog power supply, specified at 2.7 V to 3.6 V, that must be decoupled to GND with a 1-μF capacitor.
3	AINP	input	Noninverting analog signal input; the true-differential input swing is -VREF to +VREF.
4	AINN	input	Inverting analog signal input; the true-differential input swing is -VREF to +VREF.
5	GND	power_in	Device ground that is the common ground for AVDD, DVDD and the digital I/O supply, and to which the internal reference return is connected.
6	CONVST	input	Convert input that also functions as the CS input in 3-wire interface mode.
7	DOUT	output	Serial data output; data on DOUT are synchronized with SCLK.
8	SCLK	input	Clock input for the serial interface with which the data on DOUT are synchronized.
9	DIN	input	Serial data input whose level at the start of a conversion selects the mode of operation (such as CS or daisy-chain mode), and which also serves as the CS input in 4-wire interface mode.
10	DVDD	power_in	Digital interface power supply, specified at 1.65 V to 3.6 V independent of AVDD, that must be decoupled to GND with a 1-μF capacitor.
