# DAC60508ZRTET

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

DAC60508ZRTET from Texas Instruments, in a WQFN-16-EP(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 | Reference pin: reference output when the internal reference is used (default), or reference input when an external reference is used; external reference input range is 1.2 V to VDD/2 with the divider disabled, or 2.4 V to VDD with the divider enabled (3.3 V to 5.5 V supply). |
| 2 | OUT0 | output | Analog buffered voltage output from DAC channel 0. |
| 3 | OUT1 | output | Analog buffered voltage output from DAC channel 1. |
| 4 | OUT2 | output | Analog buffered voltage output from DAC channel 2. |
| 5 | OUT3 | output | Analog buffered voltage output from 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 (absolute maximum VDD to GND is 6 V). |
| 8 | OUT4 | output | Analog buffered voltage output from DAC channel 4. |
| 9 | OUT5 | output | Analog buffered voltage output from DAC channel 5. |
| 10 | OUT6 | output | Analog buffered voltage output from DAC channel 6. |
| 11 | OUT7 | output | Analog buffered voltage output from DAC channel 7. |
| 12 | CS | input | Active-low serial data enable and frame synchronization input; when low it enables the serial interface input shift register. |
| 13 | SCLK | input | Serial interface clock input, supporting up to 50 MHz. |
| 14 | SDI | input | Serial data input; data are clocked into the input shift register on each falling edge of SCLK. |
| 15 | SDO/ALARM | output | Serial data output (default), high impedance when CS is high, with edge selectable by the FSDO bit; alternatively configurable as an open-drain ALARM output for CRC or reference alarm events, which requires a 10 kΩ pull-up to VIO. |
| 16 | VIO | power_in | IO supply voltage, 1.7 V to 5.5 V, setting the operating voltage of the serial interface. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
