DAC B Voltage Output.
DAC A Voltage Output.
Negative Power Supply Input. Specified range of operation 0 V to –5.5 V.
DAC A Reference Voltage Input Terminal. Establishes DAC A full-scale output voltage. Pin can
be tied to V
DD
or V
SS
pin.
DAC B Reference Voltage Input Terminal. Establishes DAC B full-scale output voltage. Pin can
be tied to V
DD
or V
SS
pin.
Ground Pin.
Load DAC Register Strobe, Level Sensitive Active Low. Transfers all Input Register data to
DAC registers. Asynchronous active low input. See Control Logic Truth Table for operation.
Resets Input and DAC Registers to All Zero Codes. Shift Register contents unchanged.
Chip Select, Active Low Input. Disables shift register loading when high. Transfers Serial Regis-
ter Data to the Input Register when
CS
returns High. Does not effect
LDAC
operation.
Schmitt Triggered Clock Input, Positive Edge Clocks Data into Shift Register.
Serial Data Input. Input data loads directly into the shift register.
