DAC5571IDBVR from Texas Instruments, in a SOT-23-6. 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	VOUT	output	Analog output voltage from the 8-bit DAC. Rail-to-rail buffered output spanning 0 V to VDD driving up to a 2 kΩ / 200 pF load; short-circuit current 50 mA at VDD=5 V.
2	GND	power_in	Ground reference point for all circuitry (analog and digital). 0 V reference for VOUT and the I2C interface.
3	VDD	power_in	Analog voltage supply input, +2.7 V to +5.5 V. Also sets the full-scale DAC output range (0 V to VDD). Typical IDD 155 µA at 5 V active, 0.2 µA in power-down.
4	SDA	bidirectional	I2C serial data input/output. Open-drain, requires external pull-up to VDD. Supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes.
5	SCL	input	I2C serial clock input. Referenced to VDD/GND logic thresholds (VIH ≥ 0.7·VDD, VIL ≤ 0.3·VDD). Requires external pull-up to VDD.
6	A0	input	Device address select input. Tie to GND or VDD to set the LSB of the 7-bit I2C slave address, allowing up to two DAC5571 devices on the same bus.
