AD5311RBRMZ-RL7 from Analog Devices, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VDD	power_in	Power supply input, 2.7 V to 5.5 V. Decouple to GND (typically with a 100 nF capacitor).
2	VLOGIC	power_in	Digital power supply for the logic interface, 1.62 V to 5.5 V. Decouple to GND. Enables 1.8 V logic compatibility independent of VDD.
3	RESET	input	Hardware reset, active low. When asserted low the device is reset: input and DAC registers load zero-scale, control register loads defaults, and external pins are ignored. Can be tied to VLOGIC if unused.
4	LDAC	input	Load DAC input, active low. Transfers the input register contents to the DAC register. Supports synchronous and asynchronous update modes; can be tied permanently low so the DAC updates whenever new data is written to the input register.
5	GND	power_in	Ground reference for all supplies and signals.
6	A0	input	Programmable I2C address bit (ADDR1) for multiple package decoding. The address pin can be updated on the fly to allow more than one AD5311R on the same bus.
7	SCL	input	I2C serial clock line. Supports fast-mode operation up to 400 kHz (fSCL max).
8	SDA	bidirectional	I2C serial data input/output line. Open-drain output; VOL = 0.4 V max at ISINK = 200 μA, VOH = VLOGIC − 0.4 V at ISOURCE = 200 μA. Requires an external pull-up resistor.
9	VREF	bidirectional	Reference input/output. By default this pin is the on-chip 2.5 V (±2.5 mV) reference output with 2 ppm/°C typical drift; it is recommended to decouple with a 10 nF capacitor to GND. Can be reconfigured as a reference input when the internal reference is disabled.
10	VOUT	output	Buffered analog output voltage from the 10-bit DAC. Rail-to-rail operation with output span programmable to 0 V to VREF (gain = 1) or 0 V to 2×VREF (gain = 2). Drive capability up to 20 mA; short-circuit current 20 mA to 50 mA typ.
