# DAC60504BRTET

**Texas Instruments** · Digital To Analog Converters (DAC) · WQFN-16(3x3)

DAC60504BRTET 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 | REF | bidirectional | Serves as the reference output when the internal reference is used (default) and as the reference input when an external reference is used. |
| 2 | OUT0 | output | Analog voltage output of DAC channel 0. |
| 3 | OUT1 | output | Analog voltage output of DAC channel 1. |
| 4 | OUT2 | output | Analog voltage output of DAC channel 2. |
| 5 | OUT3 | output | Analog voltage output of DAC channel 3. |
| 6 | GND | power_in | Ground reference point for all circuitry on the device. |
| 7 | VDD | power_in | Analog supply voltage, 2.7 V to 5.5 V. |
| 8 | GAIN | input | Sets the initial buffer gain at power-up or reset: tied to GND gives gain 1 and tied to VIO gives gain 2, and changes after power-up have no effect. |
| 9 | RSTSEL | input | Selects the reset value of all four DACs: tied to GND resets to zero scale and connected to VIO resets to midscale. |
| 10 | REFDIV | input | Sets the reference divider at power-up or reset: tied to GND leaves the reference undivided and tied to VIO divides it by 2, and changes after power-up have no effect. |
| 11 | LDAC | input | A high-to-low transition updates the outputs of channels configured in synchronous mode simultaneously, and the pin can be tied permanently to GND. |
| 12 | CS | input | Active-low serial data enable and frame synchronization input that enables the serial interface shift register when low. |
| 13 | SCLK | input | Serial interface clock input. |
| 14 | SDI | input | Serial data input, clocked into the input shift register on each SCLK falling edge. |
| 15 | SDO/ALARM | output | Serial data output by default, high impedance when CS is high; it can instead be configured as an open-drain ALARM output for CRC or reference alarms, which requires a 10 kΩ pull-up to VIO. |
| 16 | VIO | power_in | Sets the serial interface I/O operating voltage, 1.7 V to 5.5 V. |
| 17 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
