# DAC7565ICPWR

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

DAC7565ICPWR 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/VREFOUT | bidirectional | Positive reference input, or reference output at 2.5V when the internal reference is used; the internal reference can source up to 20mA at this pin. |
| 4 | AVDD | power_in | Power-supply input, 2.7V to 5.5V. |
| 5 | VREFL | input | Negative reference input; VREFL must be below VREFH, with VREFL limited to AVDD/2 maximum per the reference input range. |
| 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 | SYNC | input | Level-triggered active-low frame sync for the input data; data are sampled on subsequent falling SCLK edges, the DAC output updates after the 24th clock, and a SYNC rising edge before the 24th clock aborts the write (Schmitt-trigger input). |
| 10 | SCLK | input | Serial clock input with data transfer rates up to 50MHz (Schmitt-trigger input). |
| 11 | DIN | input | Serial data input, clocked into the 24-bit input shift register on each falling SCLK edge (Schmitt-trigger input). |
| 12 | IOVDD | power_in | Digital input-output power supply, 1.8V to 5.5V per the electrical characteristics. |
| 13 | RST | input | Asynchronous active-low reset that sets all DAC channels to zero-scale (RSTSEL = 0) or mid-scale (RSTSEL = 1). |
| 14 | RSTSEL | input | Reset select: when low, input coding is binary; when high, input coding is two's complement. |
| 15 | ENABLE | input | Active-low enable that connects the SPI interface to the serial port. |
| 16 | LDAC | input | Load DACs input, rising-edge triggered, which loads all DAC registers. |
