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 TLV5614.
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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
