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

DAC8565ICPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUTA | output | Analog output from DAC A, output range 0V to VREF with ±20mA drive capability. |
| 2 | VOUTB | output | Analog output from DAC B, output range 0V to VREF with ±20mA drive capability. |
| 3 | VREFH/VREFOUT | bidirectional | Voltage reference input/output; provides 2.5V when internal reference is used, accepts external reference input from 0V to AVDD. |
| 4 | AVDD | power_in | Analog power supply input, operating range 2.7V to 5.5V. |
| 5 | VREFL | input | Negative voltage reference input, accepts 0V to AVDD/2V. |
| 6 | GND | power_in | Ground return for all analog and digital circuitry. |
| 7 | VOUTC | output | Analog output from DAC C, output range 0V to VREF with ±20mA drive capability. |
| 8 | VOUTD | output | Analog output from DAC D, output range 0V to VREF with ±20mA drive capability. |
| 9 | SYNC | input | Level-triggered active-low frame synchronization input; enables shift register when low, sampled on SCLK falling edges. |
| 10 | SCLK | input | Serial clock input accepting frequencies up to 50MHz; data clocked on falling edges. |
| 11 | DIN | input | Serial data input sampled on SCLK falling edges; MSB transmitted first in 24-bit frame. |
| 12 | IOVDD | power_in | Digital input-output power supply, operating range 1.8V to 5.5V. |
| 13 | RST | input | Asynchronous active-low reset; resets all DAC outputs to zero-scale or midscale per RSTSEL. |
| 14 | RSTSEL | input | Reset select input; low selects zero-scale/binary mode, high selects midscale/two's complement. |
| 15 | ENABLE | input | Active-low enable control input; HIGH disables SPI interface. |
| 16 | LDAC | input | Load DACs rising-edge triggered input; synchronously updates all DAC outputs from buffers. |
