# DAC5311IDCKR

**Texas Instruments** · Digital To Analog Converters (DAC) · SOT-363-6

DAC5311IDCKR from Texas Instruments, in a SOT-363-6. 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 | Level-triggered control input (active low) for frame synchronization of input data; when SYNC goes low, input shift register is enabled and data are clocked in on falling edges. |
| 2 | SCLK | input | Serial clock input for data transfer at rates up to 50 MHz. |
| 3 | DIN | input | Serial data input; data are clocked into the 16-bit input shift register on the falling edge of SCLK. |
| 4 | AVDD/VREF | power_in | Power supply input and reference voltage; 2.0 V to 5.5 V. |
| 5 | GND | power_in | Ground reference point for all circuitry on the part. |
| 6 | VOUT | output | Analog output voltage from DAC with rail-to-rail operation; output range 0 V to AVDD. |
