PIN CONFIGURATION AND FUNCTION DESCRIPTIONS

Pin No. Mnemonic
Function
1
I
OUT1
DAC Current Output.
2
I
OUT2
DAC Analog Ground. This pin should normally be tied to the analog ground of the system.
3
GND
Digital Ground Pin.
4
SCLK
Serial Clock Input. Data is clocked into the input shift register on each falling edge of the serial clock input.
This device can accommodate clock rates of up to 50 MHz.
5
SDIN
Serial Data Input. Data is clocked into the 8-bit input register on each falling edge of the serial clock input.
6
SYNC
Active Low Control Input. This is the frame synchronization signal for the input data. When SYNC goes low, it powers
on the SCLK and DIN buffers and the input shift register is enabled. Data is transferred on each falling edge of the
following 8 clocks.
7
LDAC
Load DAC Input. Updates the DAC output. The DAC is updated when this signal goes low or alternatively; if this line
is held permanently low, an automatic update mode is selected whereby the DAC is updated after 8 SCLK falling
edges with SYNC low.
8
V
DD
Positive Power Supply Input. This part can be operated from a supply of 2.5 V to 5.5 V.
9
V
REF
DAC Reference Voltage Input Terminal.
10
R
FB
DAC Feedback Resistor Pin. Establishes voltage output for the DAC by connecting to external amplifier output.
