DAC53204RTER from TEXAS INSTRUMENTS, in a WQFN-16(3x3). 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 | FB3 | input | Voltage feedback pin for channel 3: in voltage-output mode connect to OUT3 for closed-loop amplifier output, and in current-output mode keep it unconnected to minimize leakage current. |
| 2 | OUT3 | output | Analog output voltage from DAC channel 3. |
| 3 | OUT2 | output | Analog output voltage from DAC channel 2. |
| 4 | FB2 | input | Voltage feedback pin for channel 2: in voltage-output mode connect to OUT2 for closed-loop amplifier output, and in current-output mode keep it unconnected to minimize leakage current. |
| 5 | GPIO/SDO | bidirectional | General-purpose input/output configurable as LDAC, PD, PROTECT, RESET, SDO, or STATUS; for STATUS and SDO connect to the IO voltage through an external pullup, and if unused connect to VDD or AGND through an external resistor. |
| 6 | SCL/SYNC | input | I2C serial interface clock or SPI chip-select input that must be connected to the IO voltage through an external pullup resistor and can ramp up before VDD. |
| 7 | A0/SDI | input | Address configuration pin for I2C (connect to VDD, AGND, SDA, or SCL) or serial data input for SPI, needing no pullup or pulldown and able to ramp up before VDD. |
| 8 | SDA/SCLK | bidirectional | Bidirectional I2C serial data bus or SPI clock input that must be connected to the IO voltage through an external pullup resistor in I2C mode and can ramp up before VDD. |
| 9 | FB1 | input | Voltage feedback pin for channel 1: in voltage-output mode connect to OUT1 for closed-loop amplifier output, and in current-output mode keep it unconnected to minimize leakage current. |
| 10 | OUT1 | output | Analog output voltage from DAC channel 1. |
| 11 | OUT0 | output | Analog output voltage from DAC channel 0. |
| 12 | FB0 | input | Voltage feedback pin for channel 0: in voltage-output mode connect to OUT0 for closed-loop amplifier output, and in current-output mode keep it unconnected to minimize leakage current. |
| 13 | CAP | power_in | External bypass capacitor connection for the internal LDO, requiring approximately 1.5 µF between CAP and AGND (CCAP range 0.5 µF to 15 µF). |
| 14 | AGND | power_in | Ground reference point for all circuitry on the device. |
| 15 | VDD | power_in | Power supply voltage input; the recommended range is 1.7 V to 5.5 V, with 0.1 µF decoupling. |
| 16 | VREF | power_in | External reference input that requires approximately 0.1 µF between VREF and AGND, must not ramp up before VDD, and needs a pullup to VDD when the external reference is not used. |
| 17 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
