Description

8
RFB
DAC Feedback Resistor. Establish voltage output for the DAC by connecting to external
amplifier output.
2
7
VREF
DAC Reference Voltage Input.
3
6
VDD
Positive Power Supply Input. These parts can operate from a supply of 2.5 V to 5.5 V.
4
5
SYNC
Active Low Control Input. This is the frame synchronization signal for the input data. Data is
loaded to the shift register upon the active edge of the following clocks.
5
4
SDIN
Serial Data Input. Data is clocked into the 16-bit input register upon the active edge of the serial
clock input. By default, in power-up mode data is clocked into the shift register upon the falling
edge of SCLK. The control bits allow the user to change the active edge to a rising edge.
6
3
SCLK
Serial Clock Input. By default, data is clocked into the input shift register upon the falling edge
of the serial clock input. Alternatively, by means of the serial control bits, the device can be
configured such that data is clocked into the shift register upon the rising edge of SCLK.

GND
Ground Pin.

IOUT1
DAC Current Output.

EPAD
Exposed pad must be connected to ground.
