I

Serial data input

DVDD

1

Digital supply

FS

7

I

Frame sync input. The falling edge of the frame sync pulse indicates the start of a serial data frame shifted out

to the TLV5627.

PD

2

I

Power-down pin. Powers down all DACs (overriding their individual power down settings), and all output stages.

This terminal is active low.

LDAC

3

I

Load DAC. When the LDAC signal is high, no DAC output updates occur when the input digital data is read into

the serial interface. The DAC outputs are only updated when LDAC is low.

REFINAB

15

I

Voltage reference input for DACs A and B.

REFINCD

10

I

Voltage reference input for DACs C and D.
