# DAC8501E

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

DAC8501E 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 with operating voltage range from +2.7V to +5.5V. |
| 2 | VREF | power_in | Reference voltage input that sets the output range of the DAC with acceptable range of 0V to VDD and input impedance of 150kΩ. |
| 3 | VFB | output | Feedback connection to the inverting input of the output amplifier allowing direct connection to the load in critical applications for improved accuracy. |
| 4 | VOUT | output | Analog output voltage from the DAC with rail-to-rail operation from 0V to VDD capable of driving 2kΩ loads in parallel with 1000pF to ground. |
| 5 | SYNC | input | Active-LOW level-triggered frame synchronization control input that enables the input shift register on LOW and acts as an interrupt if taken HIGH before the 24th falling edge of SCLK. |
| 6 | SCLK | input | Serial clock input operating at rates up to 30MHz maximum frequency for clocking data into the 24-bit shift register on falling clock edges. |
| 7 | DIN | input | Serial data input clocked into the 24-bit shift register on falling edges of SCLK in MSB-first format comprising 6 don't-care bits, 2 control bits (PD1, PD0), and 16 data bits. |
| 8 | GND | power_in | Ground reference point for all circuitry on the device that carries all return currents from both digital and analog sections. |
