# DAC8830IBDR

**Texas Instruments** · Digital To Analog Converters (DAC) · SOIC-8

DAC8830IBDR from Texas Instruments, in a SOIC-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 | VOUT | output | Analog output of the DAC; unipolar 0 V to +VREF and unbuffered, with about 6.25 kΩ output impedance. |
| 2 | AGND | power_in | Analog ground; AGND to DGND must stay within -0.3 V to +0.3 V per the absolute maximum ratings. |
| 3 | VREF | power_in | Voltage reference input; usable range is 1.25 V to VDD, and references below 1.25 V reduce accuracy. |
| 4 | CS | input | Chip select input, active low; data are not clocked into SDI unless CS is low. |
| 5 | SCLK | input | Serial clock input with Schmitt-trigger input, supporting SPI clock rates up to 50 MHz. |
| 6 | SDI | input | Serial data input, latched into the input register on the rising edge of SCLK. |
| 7 | DGND | power_in | Digital ground; digital inputs are referenced to DGND with absolute maximum range -0.3 V to VDD + 0.3 V. |
| 8 | VDD | power_in | Analog power supply, +3 V to +5 V per the terminal functions; the electrical specification allows 2.7 V to 5.5 V and the absolute maximum is +7 V to AGND. |
