# DAC8311IDCKT

**Texas Instruments** · Digital To Analog Converters (DACs) · SC-70-6(SOT-363)

DAC8311IDCKT from Texas Instruments, in a SC-70-6(SOT-363). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SYNC | input | Active-low, level-triggered frame synchronization input for the serial interface. When SYNC goes low, the input shift register is enabled and data is clocked in on the falling edges of SCLK; the DAC is updated after the 16th clock cycle unless SYNC is taken high early (in which case the rising edge acts as an interrupt and the write is ignored). |
| 2 | SCLK | input | Serial clock input. Data on DIN is clocked into the shift register on the falling edge of SCLK at rates up to 50 MHz. Schmitt-triggered logic input. |
| 3 | DIN | input | Serial data input. Data is clocked into the 16-bit (DAC8311) input shift register on the falling edge of SCLK while SYNC is low. |
| 4 | AVDD/VREF | power_in | Analog power supply input and reference voltage for the DAC, +2 V to +5.5 V. AVDD sets the full-scale output range (VOUT = 0 to AVDD). Decouple to GND with appropriate bypass capacitors. |
| 5 | GND | power_in | Ground reference for all analog and digital circuitry on the device. |
| 6 | VOUT | output | Analog voltage output from the DAC. The rail-to-rail output amplifier swings from 0 V to AVDD and can drive a 2 kΩ load with up to 200 pF capacitance while maintaining stability. |

## CAD (KiCad official)

- Symbol: `DAC8311IDCKT`
- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`
- 3D model: SC-70-6(SOT-363) (KiCad packages3D, STEP)
- 3D model files: `dac8311idckt-etched.step` / `dac8311idckt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dac8311idckt.step` / `dac8311idckt.glb` are the bare package body.
