DAC A, B, C, D Analog ground.
DAC A, B, C, D Current output.
DAC A, B, C, D Reference voltage input terminal. Establishes DAC A, B, C, D full-scale
output voltage. Can be tied to V
DD
.
Establish voltage output for DAC A, B, C, D by connecting to external amplifier output.
MSB Bit set during a reset pulse (RS) or at system power on if tied to ground or V
DD
.
Reset pin, active low. Input register and DAC registers are set to all zeros or half scale
code (8000h) determined by the voltage on the MSB pin. Register data = 8000h when
MSB = 1.
Positive power supply input. Specified range of operation 5 V
±
10%.
Chip-select; active low input. Disables shift register loading when high. Transfers shift
register data to input register when CS/LDAC goes high. Does not affect LDAC operation.
Clock input; positive edge triggered clocks data into shift register
Serial data input; data loads directly into the shift register.
Not connected; leave floating.
Serial data output; input data loads directly into shift register. Data appears at SDO, 19
clock pulses after input at the SDI pin.
Load DAC register strobe; level sensitive active low. Tranfers all input register data to the
DAC registers. Asynchronous active low input. See Table 1 for operation.
High current analog force ground.
Negative bias power-supply input. Specified range of operation -0.3 V to -5.5 V.
Digital ground.
