Function
Analog Ground.
DAC A Voltage Output.
DAC Reference voltage input terminal. Establishes DAC full-scale output voltage. Pin can be tied to V
DD
pin.
Digital Ground. Should be tied to analog GND.
Chip Select, active low input. Disables shift register loading when high. Does not effect
LDA
or
LDB
operation.
Clock input, positive edge clocks data into shift register, MSB data bit first.
Serial Data Input, input data loads directly into the shift register.
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.
Resets DAC register to zero condition or half-scale, depending on MSB pin logic level. Asynchronous active
low input.
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.
Digital Input: Logic High presets DAC registers to half-scale 800
H
(sets MSB bit to one) when the
RS
pin is
strobed; Logic Low clears all DAC registers to zero (000
H
) when the
RS
pin is strobed.
Active low shutdown control input. Does not affect register contents as long as power is present on V
DD
. 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.
Positive power supply input. Specified range of operation +2.7 V to +5.5 V
DAC B Voltage Output.
