# DAC7811IDGSR

**Texas Instruments** · Digital To Analog Converters (DACs) · VSSOP-10-0.5mm

DAC7811IDGSR from Texas Instruments, in a VSSOP-10-0.5mm. 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 | IOUT1 | output | DAC current output. |
| 2 | IOUT2 | passive | DAC analog ground, normally tied to the analog ground of the system. |
| 3 | GND | power_in | Ground pin. |
| 4 | SCLK | input | Serial clock input; data is clocked into the input shift register on the falling edge by default, or the rising edge if configured via the serial control bits. |
| 5 | SDIN | input | Serial data input; data is clocked into the 16-bit input register on the active edge of SCLK (falling edge by default at power-up). |
| 6 | SYNC | input | Active-low frame synchronization input; when low it powers on the SCLK and DIN buffers and enables the input shift register, with data latched on the 16th active clock edge in stand-alone mode. |
| 7 | SDO | output | Serial data output for daisy-chaining and readback of DAC register contents, clocked out on the edge opposite the active loading edge. |
| 8 | VDD | power_in | Positive power supply input, operable from 2.7 V to 5.5 V. |
| 9 | VREF | power_in | DAC reference voltage input, recommended range -15 V to 15 V. |
| 10 | RFB | output | DAC feedback resistor pin; connect to the external amplifier output to establish the DAC voltage output. |
