# DAC53401DSGR

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

DAC53401DSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | A0 | input | Four-state address input pin for selecting I2C slave address based on connection to AGND, VDD, SCL, or SDA. |
| 2 | SCL | input | Serial clock input for I2C communication; must be connected to supply voltage with external pullup resistor and supports standard, fast, and fast+ modes. |
| 3 | SDA | bidirectional | Bidirectional data line for I2C communication; must be connected to supply voltage with external pullup resistor; data clocked into or out of the input register. |
| 4 | CAP | input | External capacitor connection for internal low-dropout regulator; 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 input with operating voltage range 1.8 V to 5.5 V. |
| 7 | FB | input | Voltage feedback input pin for force-sense operation and internal reference adjustment. |
| 8 | OUT | output | Analog output voltage from the DAC; output voltage range 0 V to VDD determined by digital input code. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
