# TLV5627CPWR

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

TLV5627CPWR 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 | DVDD | power_in | Digital supply for the serial interface, which can be any value between 2.7 V and 5.5 V and is independent of AVDD. |
| 2 | PD | input | Active-low power-down pin that powers down all DACs (overriding their individual power-down settings) and all output stages. |
| 3 | LDAC | input | Load DAC: when high, no DAC output updates occur as input data is read into the serial interface, and the DAC outputs update only when LDAC is low. |
| 4 | DIN | input | Serial data input, shifted in MSB first on the falling edges of SCLK. |
| 5 | SCLK | input | Serial clock input, with a maximum serial clock rate of 20 MHz. |
| 6 | CS | input | Chip select input, active low; the device is enabled only when CS is low. |
| 7 | FS | input | Frame sync input; the falling edge of the frame sync pulse indicates the start of a serial data frame shifted into the TLV5627. |
| 8 | DGND | power_in | Digital ground for the serial interface supply. |
| 9 | AGND | power_in | Analog ground for the DACs, reference buffers and output buffers. |
| 10 | REFINCD | input | Voltage reference input for DACs C and D, with an input voltage range of 0 V to AVDD − 1.5 V. |
| 11 | OUTD | output | DAC D voltage output from the rail-to-rail x2 gain output buffer. |
| 12 | OUTC | output | DAC C voltage output from the rail-to-rail x2 gain output buffer. |
| 13 | OUTB | output | DAC B voltage output from the rail-to-rail x2 gain output buffer. |
| 14 | OUTA | output | DAC A voltage output from the rail-to-rail x2 gain output buffer. |
| 15 | REFINAB | input | Voltage reference input for DACs A and B, with an input voltage range of 0 V to AVDD − 1.5 V. |
| 16 | AVDD | power_in | Analog supply for the DACs, reference buffers and output buffers, which can be any value between 2.7 V and 5.5 V and is independent of DVDD. |
