# DAC8163SQDGSRQ1

**Texas Instruments** · Digital To Analog Converters (DACs) · VSSOP-10-0.5mm

DAC8163SQDGSRQ1 from Texas Instruments, in a VSSOP-10-0.5mm. 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 | VOUTA | output | Analog output voltage from DAC-A. |
| 2 | VOUTB | output | Analog output voltage from DAC-B. |
| 3 | GND | power_in | Ground reference point for all circuitry on the device. |
| 4 | LDAC | input | Negative edge-triggered LDAC input for simultaneous DAC updates in asynchronous mode; must be tied to GND or held low for synchronous updates. |
| 5 | CLR | input | Asynchronous falling-edge-sensitive clear input that loads mid-scale (DACxx63-Q1) to all input and DAC registers; exits clear mode on the 24th falling edge of the next write. |
| 6 | SYNC | input | Active-low frame synchronization input with Schmitt-trigger logic; enables the input shift register when low, and DAC output updates after the 24th clock falling edge. |
| 7 | SCLK | input | Serial clock input with Schmitt-trigger logic; data can be transferred at rates up to 50 MHz. |
| 8 | DIN | input | Serial data input with Schmitt-trigger logic; data are clocked into the 24-bit input shift register on each falling edge of SCLK. |
| 9 | AVDD | power_in | Power-supply input, 2.7 V to 5.5 V. |
| 10 | VREFIN/VREFOUT | bidirectional | Bidirectional voltage reference pin; 2.5-V output if the internal reference is used. |
