# DAC8168IAPW

**Texas Instruments** · Digital To Analog Converters (DAC) · TSSOP-14

DAC8168IAPW from Texas Instruments, in a TSSOP-14. 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 | SYNC | input | Active-low, level-triggered frame synchronization input (Schmitt-trigger); the DAC output updates after the 32nd clock, and a rising SYNC edge before the 31st clock edge aborts the write sequence. |
| 2 | AVDD | power_in | Power-supply input, 2.7 V to 5.5 V. |
| 3 | VOUTA | output | Analog output voltage from DAC A. |
| 4 | VOUTC | output | Analog output voltage from DAC C. |
| 5 | VOUTE | output | Analog output voltage from DAC E. |
| 6 | VOUTG | output | Analog output voltage from DAC G. |
| 7 | VREFIN/VREFOUT | bidirectional | Positive reference input / reference output, 2.5 V when the internal reference is used; for grades A and B the external VREFIN (max) must be ≤ AVDD. |
| 8 | VOUTH | output | Analog output voltage from DAC H. |
| 9 | VOUTF | output | Analog output voltage from DAC F. |
| 10 | VOUTD | output | Analog output voltage from DAC D. |
| 11 | VOUTB | output | Analog output voltage from DAC B. |
| 12 | GND | power_in | Ground reference point for all circuitry on the device. |
| 13 | DIN | input | Serial data input clocked into the 32-bit input shift register on each falling SCLK edge (Schmitt-trigger logic input). |
| 14 | SCLK | input | Serial clock input; data can be transferred at rates up to 50 MHz (Schmitt-trigger logic input). |
