**Texas Instruments** · Digital To Analog Converters (DAC) · TSSOP-16

DAC8574IPWR from Texas Instruments, in a TSSOP-16. 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. |
| 2 | VOUTB | output | Analog output voltage from DAC B. |
| 3 | VREFH | input | Positive reference voltage input that sets the DAC output range; the output spans 0 to VREFH. |
| 4 | VDD | power_in | Analog voltage supply input; the datasheet specifies 2.7 V to 5.5 V. |
| 5 | VREFL | input | Negative reference voltage input; the datasheet requires VREFL < VREFH. |
| 6 | GND | power_in | Ground reference point for all circuitry on the part. |
| 7 | VOUTC | output | Analog output voltage from DAC C. |
| 8 | VOUTD | output | Analog output voltage from DAC D. |
| 9 | LDAC | input | Hardware synchronous VOUT update input, used to update all DAC outputs simultaneously. |
| 10 | SCL | input | Serial clock input for the I2C interface (up to 3.4 Mbps high-speed mode). |
| 11 | SDA | bidirectional | Serial data input for the I2C interface; the I2C data line is bidirectional. |
| 12 | IOVDD | power_in | I/O voltage supply input for the digital interface pins. |
| 13 | A0 | input | Device address select for the I2C interface. |
| 14 | A1 | input | Device address select for the I2C interface. |
| 15 | A2 | input | Device address select for extended addressing. |
| 16 | A3 | input | Device address select for extended addressing. |
