# DAC8568IDPW

**Texas Instruments** · Digital To Analog Converters (DAC) · TSSOP-16

DAC8568IDPW from Texas Instruments, in a TSSOP-16. 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 | LDAC | input | Load DACs input; the datasheet pin table gives no further limits or timing for this function. |
| 2 | SYNC | input | Active-low, level-triggered frame sync input that enables the input shift register so data are sampled on subsequent falling SCLK edges, the DAC output updates after the 32nd clock, and a SYNC rising edge before the 31st clock edge aborts the write; Schmitt-Trigger input. |
| 3 | AVDD | power_in | Power-supply input, 2.7V to 5.5V. |
| 4 | VOUTA | output | Analog output voltage from DAC A. |
| 5 | VOUTC | output | Analog output voltage from DAC C. |
| 6 | VOUTE | output | Analog output voltage from DAC E. |
| 7 | VOUTG | output | Analog output voltage from DAC G. |
| 8 | VREFIN/VREFOUT | bidirectional | Positive reference input or reference output (2.5V when the internal reference is used); external VREFIN max is AVDD for grades A/B and AVDD/2 for grades C/D. |
| 9 | CLR | input | Asynchronous clear input; the datasheet pin table gives no further limits or behavior for this function. |
| 10 | VOUTH | output | Analog output voltage from DAC H. |
| 11 | VOUTF | output | Analog output voltage from DAC F. |
| 12 | VOUTD | output | Analog output voltage from DAC D. |
| 13 | VOUTB | output | Analog output voltage from DAC B. |
| 14 | GND | power_in | Ground reference point for all circuitry on the device. |
| 15 | DIN | input | Serial data input clocked into the 32-bit input shift register on each falling SCLK edge; Schmitt-Trigger logic input. |
| 16 | SCLK | input | Serial clock input supporting data transfer at rates up to 50MHz; Schmitt-Trigger logic input. |
