AD7988-1BRMZ 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 referred to the GND pin, with a stated VREF range of 2.4 V to 5.1 V; decouple GND closely to REF with a 10 µF capacitor.
2	VDD	power_in	Power supply; the absolute maximum rating for VDD to GND is −0.3 V to +3 V.
3	IN+	input	Analog input referred to IN−, with the input voltage range (IN+ minus IN−) of 0 V to VREF.
4	IN−	input	Analog input ground sense; connect to the analog ground plane or to a remote sense ground.
5	GND	power_in	Power supply ground.
6	CNV	input	Convert input whose leading edge starts a conversion and selects chain or CS mode; in CS mode SDO is enabled when CNV is low, and in chain mode data is read when CNV is high.
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: chain mode if low at the CNV rising edge (data output on SDO with a 16 SCK-cycle delay), or CS mode if high.
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.
