DESCRIPTION
AGND
9
Analog ground
AVDD
16
Analog supply
CS
6
I
Chip select. This terminal is active low.
DGND
8
Digital ground
DIN
4
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.
SCLK
5
I
Serial clock input
OUTA
14
O
DAC A output
OUTB
13
O
DAC B output
OUTC
12
O
DAC C output
OUTD
11
O
DAC D output

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.
