# TLV5638IDR

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

TLV5638IDR from Texas Instruments, in a SOIC-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 | DIN | input | Digital serial data input for the 16-bit serial word, which contains 4 control bits and 12 data bits. |
| 2 | SCLK | input | Digital serial clock input that shifts data into the device. |
| 3 | CS | input | Active-low chip select that enables or disables the digital inputs. |
| 4 | OUTA | output | DAC A analog voltage output. |
| 5 | AGND | power_in | Ground reference for the analog circuitry. |
| 6 | REF | bidirectional | Analog reference voltage input/output; the reference input range is -0.3 V to VDD + 0.3 V per the absolute maximum ratings. |
| 7 | OUTB | output | DAC B analog voltage output. |
| 8 | VDD | power_in | Positive power supply, with an absolute maximum of 7 V referenced to AGND. |
