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 | CLK | input | Serial clock input. Positive edge triggered; clocks data into the shift register on the rising edge. Supports up to 50 MHz. |+| 2 | SDI | input | Serial data input. Data loads directly into the 16-bit shift register MSB first; extra leading bits are ignored. |+| 3 | RFB | passive | Internal matching feedback resistor. Connect to the output of the external I-to-V op amp to set the transimpedance gain and provide temperature tracking with the DAC ladder. |+| 4 | VREF | input | DAC reference input pin. Establishes DAC full-scale output current; accepts ±10-V input with constant input resistance versus code. |+| 5 | IOUT | output | DAC current output. Connects to the inverting input of an external precision I-to-V op amp (2-mA full-scale current with VREF = 10 V). |+| 6 | GND | power_in | Analog and digital ground reference for the device. |+| 7 | VDD | power_in | Positive power supply input. Specified operating range 2.7 V to 5.5 V; typical IDD = 2 µA. |+| 8 | CS | input | Active-low chip select digital input. Frames the serial transfer and transfers shift register data to the DAC register on the rising edge. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSSOP-8 |+| Category | Data Acquisition |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `DAC8811IBDGKR`+- `DAC8811IBDGKRICDGK`+- `DAC8811IBDGKRICDGKR`+- `DAC8811IBDGKRIBDRB`+- `DAC8811IBDGKRIBDRBR`+- `DAC8811IBDGKRICDRB`+- `DAC8811IBDGKRICDRBR`++## CAD (KiCad official)++- Symbol: `DAC8811IBDGKR`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/dac8811) (31 pp, sha256 `491af32e06f60240`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
