**Texas Instruments** · Digital To Analog Converters (DAC) · WSON-8-EP(2x2)

DAC53401DSGT from Texas Instruments, in a WSON-8-EP(2x2). 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 | A0 | input | Four-state address input selectable as AGND, VDD, SDA, or SCL to set device slave address. |
| 2 | SCL | input | Serial interface clock input, must be connected to supply voltage with external pullup resistor. |
| 3 | SDA | bidirectional | Bidirectional serial data line for I²C communication, must be connected to supply voltage with external pullup resistor. |
| 4 | CAP | input | External capacitor connection for internal LDO, connect 0.5 µF to 15 µF capacitor between CAP and AGND. |
| 5 | AGND | power_in | Ground reference point for all circuitry on the device. |
| 6 | VDD | power_in | Analog supply voltage, operating range 1.8 V to 5.5 V. |
| 7 | FB | input | Voltage feedback pin for DAC output compensation in control applications. |
| 8 | OUT | output | Analog output voltage from DAC, 0 V to 5.5 V when VDD is used as reference. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
