DAC8571IDGKR from Texas Instruments, in a MSOP-8. 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 | Analog voltage supply input, 2.7 V to 5.5 V operating range. |
| 2 | VREF | power_in | Positive reference voltage input, 0 V to VDD operating range, 140 kΩ input impedance. |
| 3 | V(SENSE) | power_in | Analog output sense input, inverting terminal of output amplifier brought out through feedback resistor for remote load sensing applications. |
| 4 | VOUT | output | Analog output voltage from DAC, 0 V to VREF operating range with rail-to-rail output capability, 10 µs settling time to ±0.003% FSR. |
| 5 | A0 | input | Device I2C address select input, determines one bit of 7-bit slave address, can be tied to VDD or GND or driven by TTL/CMOS logic levels. |
| 6 | SCL | input | Serial clock input for I2C interface supporting standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) operation modes. |
| 7 | SDA | bidirectional | Serial data input/output for I2C interface, bidirectional open-drain signal supporting all I2C speed modes. |
| 8 | GND | power_in | Ground reference point for all circuitry on the part. |
