It uses its own supply as the reference, so the full-scale output tracks AVDD and no external reference is needed, and it settles quickly at low power. The small size and simple interface make it a cheap way to add a programmable analog level, a bias, a setpoint, or a contrast voltage, next to the circuit it controls. The 8-bit member of the DAC5311/6311/7311 family.++## 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 are clocked in on the falling edges of SCLK; the DAC is updated after the 16th clock cycle unless SYNC is taken high early, which aborts the write and asserts SYNC as an interrupt. |+| 2 | SCLK | input | Serial clock input. Data on DIN are transferred into the input shift register on the falling edge of SCLK at rates up to 50 MHz. Schmitt-triggered CMOS input. |+| 3 | DIN | input | Serial data input. Data are clocked into the 16-bit input shift register on the falling edge of SCLK. Compatible with SPI, QSPI, Microwire, and DSP interfaces. |+| 4 | AVDD/VREF | power_in | Combined analog supply and reference input, 2.0 V to 5.5 V. Sets the DAC full-scale output range (VOUT range is 0 V to AVDD). Bypass to GND with a low-ESR ceramic capacitor close to the pin. |+| 5 | GND | power_in | Ground reference for all analog and digital circuitry on the device. |+| 6 | VOUT | output | Analog voltage output from the 8-bit DAC. Rail-to-rail output buffer amplifier drives 0 V to AVDD; stable with capacitive loads up to 1000 pF (RL = 2 kΩ). DC output impedance is 0.5 Ω. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Voltage-output DAC |+| Resolution | 8-bit |+| Interface | SPI (3-wire) |+| Reference | AVDD (supply) |+| Settling | Fast, low glitch |+| Supply | 2.7-5.5 V |+| Package | SC70-6 |++## Ordering variants++- `DAC5311IDCKR (SC70-6)`+- `DAC6311IDCKR (10-bit)`+- `DAC7311IDCKR (12-bit)`++## CAD (KiCad official)++- Symbol: `Analog_DAC:DAC5311xDCK (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SC70-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/dac5311.pdf) (40 pp, sha256 `212625aa6189ace3`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
