# DAC8531E

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

DAC8531E from Texas Instruments, in a VSSOP-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 from +2.7V to +5.5V. |
| 2 | VREF | power_in | Reference voltage input with input range 0 to VDD V and input impedance of 150 kΩ. |
| 3 | VFB | input | Feedback connection for the output amplifier, brought out to allow connection directly to the load for improved accuracy. |
| 4 | VOUT | output | Analog output voltage from DAC with rail-to-rail operation from 0V to VDD and settling time of 10 µs to ±0.003% FSR. |
| 5 | SYNC | input | Level-triggered control input (active LOW) that enables the input shift register and gates data transfer on falling edges of SCLK. |
| 6 | SCLK | input | Serial clock input supporting data transfer at rates up to 30MHz. |
| 7 | DIN | input | Serial data input where data is clocked into the 24-bit shift register on the falling edge of SCLK. |
| 8 | GND | power_in | Ground reference point for all device circuitry. |
