# DAC80508ZRTER

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

DAC80508ZRTER 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 voltage output pin for internal reference mode (default) or external reference input pin. |
| 2 | OUT0 | output | Analog output voltage from DAC channel 0. |
| 3 | OUT1 | output | Analog output voltage from DAC channel 1. |
| 4 | OUT2 | output | Analog output voltage from DAC channel 2. |
| 5 | OUT3 | output | Analog output voltage from DAC channel 3. |
| 6 | GND | power_in | Ground reference point for all circuitry on the device. |
| 7 | VDD | power_in | Analog supply voltage, operating range 2.7 V to 5.5 V. |
| 8 | OUT4 | output | Analog output voltage from DAC channel 4. |
| 9 | OUT5 | output | Analog output voltage from DAC channel 5. |
| 10 | OUT6 | output | Analog output voltage from DAC channel 6. |
| 11 | OUT7 | output | Analog output voltage from DAC channel 7. |
| 12 | CS | input | Active low frame synchronization signal for serial interface (enables input shift register when low). |
| 13 | SCLK | input | Serial interface clock input. |
| 14 | SDI | input | Serial interface data input (data clocked on falling edge of SCLK). |
| 15 | SDO/ALARM | tri_state | Serial data output (high-Z when CS high, default) or open-drain alarm output for CRC/reference alarm indication (requires 10 kΩ pull-up to VIO). |
| 16 | VIO | power_in | IO supply voltage, operating range 1.7 V to 5.5 V, for serial interface operation. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
