PIN FUNCTION DESCRIPTIONS
Pin
No.
Name
Function
1
AGND
Analog Ground.
2VOUTA
DAC A Voltage Output.
3VREF
DAC Reference voltage input terminal. Establishes DAC full-scale output voltage. Pin can be tied to VDD pin.
4
DGND
Digital Ground. Should be tied to analog GND.
5
CS
Chip Select, active low input. Disables shift register loading when high. Does not effect
LDA or LDB operation.
6
CLK
Clock input, positive edge clocks data into shift register, MSB data bit first.
7
SDI
Serial Data Input, input data loads directly into the shift register.
8
LDA
Load DAC register strobe, level sensitive active low. Transfers shift register data to DAC A register. Asyn-
chronous active low input. See Control Logic Truth Table for operation.
9
RS
Resets DAC register to zero condition or half-scale, depending on MSB pin logic level. Asynchronous active
low input.
10
LDB
Load DAC register strobe, level-sensitive active low. Transfers shift register data to DAC B register. Asyn-
chronous active low input. See Control Logic Truth Table for operation.
11
MSB
Digital Input: Logic High presets DAC registers to half-scale 800H (sets MSB bit to one) when the RS pin is
strobed; Logic Low clears all DAC registers to zero (000H) when the RS pin is strobed.
12
SHDN
Active low shutdown control input. Does not affect register contents as long as power is present on VDD. New
data can be loaded into the shift register and DAC register during shutdown. When device is powered up the
most recent data loaded into the DAC register will control the DAC output.
13
VDD
Positive power supply input. Specified range of operation +2.7 V to +5.5 V
14
VOUTB
DAC B Voltage Output.
