AD7303BRZ from Analog Devices, in a SOIC-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	VOUT A	output	Analog output voltage from DAC A, with an output amplifier that swings rail to rail.
2	VDD	power_in	Power supply input operating from +2.7 V to +5.5 V, which should be decoupled to GND.
3	GND	power_in	Ground reference point for all circuitry on the part.
4	REF	bidirectional	External reference input for both DACs with range 1 V to VDD/2 when INT/EXT bit is set to logic one, and outputs the internal reference voltage for decoupling when the internal reference is selected (do not connect external voltages then).
5	SCLK	input	Serial clock logic input; data is clocked into the input shift register on the rising edge at rates up to 30 MHz.
6	DIN	input	Serial data input to the 16-bit shift register (8 data bits and 8 control bits), clocked in on the rising edge of the clock.
7	SYNC	input	Active-low level-triggered frame synchronization input that enables the input shift register when low, with the rising edge updating the relevant registers.
8	VOUT B	output	Analog output voltage from DAC B, with an output amplifier that swings rail to rail.
