DAC8831ICD from Texas Instruments, in a SOIC-14. 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	RFB	passive	Feedback resistor; connect to the output of the external operational amplifier in bipolar mode.
2	VOUT	output	Analog output of the DAC (unbuffered, about 6.25 kΩ output impedance, 0 to +VREF unipolar).
3	AGNDF	power_in	Analog ground (Force) Kelvin connection.
4	AGNDS	power_in	Analog ground (Sense) Kelvin connection.
5	VREF-S	power_in	Voltage reference input (Sense); connect to external voltage reference (1.25 V to VDD range).
6	VREF-F	power_in	Voltage reference input (Force); connect to external voltage reference (1.25 V to VDD range).
7	CS	input	Chip select input, active low; data are not clocked into SDI unless CS is low.
8	SCLK	input	Serial clock input (up to 50 MHz).
9	NC	unconnected	No internal connection.
10	SDI	input	Serial data input; data are latched into the input register on the rising edge of SCLK.
11	LDAC	input	Load DAC control input, active low; when low the DAC latch is simultaneously updated with the content of the input register.
12	DGND	power_in	Digital ground.
13	INV	passive	Junction point of internal scaling resistors; connect to the external operational amplifier inverting input in bipolar mode.
14	VDD	power_in	Analog power supply, +3 V to +5 V (2.7 V to 5.5 V operating range).
