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

DAC8565IAPWR 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 voltage from DAC A. |
| 2 | VOUTB | output | Analog output voltage from DAC B. |
| 3 | VREFH/VREFOUT | bidirectional | Positive reference input or 2.5V reference output when internal reference is used; sources up to 20mA. |
| 4 | AVDD | power_in | Power-supply input, 2.7V to 5.5V. |
| 5 | VREFL | input | Negative reference input, 0V to AVDD/2V. |
| 6 | GND | power_in | Ground reference point. |
| 7 | VOUTC | output | Analog output voltage from DAC C. |
| 8 | VOUTD | output | Analog output voltage from DAC D. |
| 9 | SYNC | input | Active-low frame synchronization input with Schmitt-Trigger logic; enables shift register when low, acts as interrupt if raised before 24th SCLK edge. |
| 10 | SCLK | input | Serial clock input with Schmitt-Trigger logic; data transferred on falling edges at rates up to 50MHz. |
| 11 | DIN | input | Serial data input with Schmitt-Trigger logic clocked into 24-bit shift register on falling SCLK edges. |
| 12 | IOVDD | power_in | Digital input-output power supply, 1.8V to 5.5V. |
| 13 | RST | input | Asynchronous active-low reset input resetting all DAC channels to zero-scale or midscale per RSTSEL state. |
| 14 | RSTSEL | input | Reset select input determining reset destination (zero-scale if low, midscale if high) and input coding mode (binary if low, two's complement if high). |
| 15 | ENABLE | input | Active-low control input enabling the SPI interface. |
| 16 | LDAC | input | Rising edge-triggered load input updating all DAC output registers simultaneously. |
