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

DAC8552IDGKT from Texas Instruments, in a MSOP-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 | VDD | power_in | Power supply input, rated 2.7V to 5.5V. |
| 2 | VREF | power_in | Reference voltage input to set DAC output range, 0V to VDD with 62kΩ input impedance. |
| 3 | VOUTB | output | DAC B analog output, 0V to VREF rail-to-rail with 10µs settling to ±0.003% FSR. |
| 4 | VOUTA | output | DAC A analog output, 0V to VREF rail-to-rail with 10µs settling to ±0.003% FSR. |
| 5 | SYNC | input | Frame synchronization input (active LOW) for serial data transfer control; Schmitt-Trigger input. |
| 6 | SCLK | input | Serial clock input supporting up to 30MHz transfer rate at 5V; Schmitt-Trigger input. |
| 7 | DIN | input | Serial data input for 24-bit shift register, data latched on SCLK falling edges; Schmitt-Trigger input. |
| 8 | GND | power_in | Ground reference for all device circuitry. |
