DESCRIPTION
Reference Input Voltage High. Sets maximum output voltage for all DACs.
DAC B Voltage Output.
DAC A Voltage Output.
Negative Analog Supply Voltage, 0V or –5V.
Ground.
Asynchronous Reset Input. Sets DAC and input registers to either mid-scale (800
H
, DAC7624) or zero-scale (000
H
, DAC7625)
when LOW.
Load DAC Input. All DAC Registers are transparent when LOW.
Data Bit 0. Least significant bit of 12-bit word.
Data Bit 1
Data Bit 2
Data Bit 3
Data Bit 4
Data Bit 5
Data Bit 6
Data Bit 7
Data Bit 8
Data Bit 9
Data Bit 10
Data Bit 11. Most significant bit of 12-bit word.
Read/Write Control Input (read = HIGH, write = LOW).
Register/DAC Select (C or D = HIGH, A or B = LOW).
Register/DAC Select (B or D = HIGH, A or C = LOW).
Chip Select Input.
Not Internally Connected. Pin has no internal connection to the device.
Positive Analog Supply Voltage, +5V nominal.
DAC D Voltage Output.
DAC C Voltage Output.
Reference Input Voltage Low. Sets minimum output voltage for all DACs.
