# DAC8811ICDGKR

**Texas Instruments** · Digital To Analog Converters (DACs) · VSSOP-8

DAC8811ICDGKR from Texas Instruments, in a VSSOP-8. 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 | CLK | input | Clock input; the positive edge triggers clocking of data into the shift register. |
| 2 | SDI | input | Serial register input; data loads directly into the shift register MSB first, and extra leading bits are ignored. |
| 3 | RFB | output | Internal matching feedback resistor that connects to the external op amp output. |
| 4 | VREF | power_in | DAC reference input that establishes the DAC full-scale voltage, with constant input resistance versus code. |
| 5 | IOUT | output | DAC current output that connects to the inverting terminal of an external precision I/V op amp. |
| 6 | GND | power_in | Analog and digital ground. |
| 7 | VDD | power_in | Positive power supply input with a specified operating range of 2.7 V to 5.5 V. |
| 8 | CS | input | Active-low chip-select; transfers shift register data to the DAC register on the rising edge (see Table 1 for operation). |
