# DAC5574IDGSR

**Texas Instruments** · Digital To Analog Converters (DAC) · MSOP-10

DAC5574IDGSR from Texas Instruments, in a MSOP-10. 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 | VOUTA | output | Analog output voltage from DAC A, which swings rail-to-rail between 0 V and VDD. |
| 2 | VOUTB | output | Analog output voltage from DAC B, which swings rail-to-rail between 0 V and VDD. |
| 3 | GND | power_in | Ground reference point for all circuitry on the part. |
| 4 | VOUTC | output | Analog output voltage from DAC C, which swings rail-to-rail between 0 V and VDD. |
| 5 | VOUTD | output | Analog output voltage from DAC D, which swings rail-to-rail between 0 V and VDD. |
| 6 | SCL | input | Serial clock input for the I2C interface; input-low threshold is 0.3×VDD and input-high threshold is 0.7×VDD (at VDD = 3 V). |
| 7 | SDA | bidirectional | Serial data input and output for the I2C interface, using the same logic input thresholds as SCL (0.3×VDD low, 0.7×VDD high at VDD = 3 V). |
| 8 | VDD | power_in | Analog voltage supply input, specified from 2.7 V to 5.5 V and setting the DAC output range. |
| 9 | A0 | input | Device address select input for the I2C interface, allowing up to four DAC5574 devices on one bus. |
| 10 | A1 | input | Device address select input for the I2C interface, allowing up to four DAC5574 devices on one bus. |
