ADS8881IDGSR

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

ADS8881IDGSR 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	passive	Positive reference input; this pin must be decoupled with a 10-μF or larger capacitor.
2	AVDD	power_in	Analog power supply; this pin must be decoupled to GND with a 1-μF capacitor.
3	AINP	passive	Noninverting analog signal input.
4	AINN	passive	Inverting analog signal input.
5	GND	power_in	Device ground, common to both the analog supply (AVDD) and digital I/O supply (DVDD); the reference return line is also internally connected to this pin.
6	CONVST	input	Convert input; also functions as the CS input in 3-wire interface mode.
7	DOUT	output	Serial data output, synchronized with SCLK.
8	SCLK	input	Clock input for the serial interface; data on DOUT is synchronized with this clock.
9	DIN	input	Serial data input; the DIN level at the start of a conversion selects the mode of operation (such as CS or daisy-chain mode), and this pin also serves as the CS input in 4-wire interface mode.
10	DVDD	power_in	Digital interface power supply; this pin must be decoupled to GND with a 1-μF capacitor.
