Description
DAC Ground Pin. This pin should typically be tied to the analog ground of the system, but can be biased to
achieve single-supply operation.
DAC Current Outputs.
DAC Feedback Resistor Pins. Establish voltage output for the DAC by connecting to an external amplifier
output.
DAC Reference Voltage Input Terminals.
Digital Ground Pin.
Selects DAC A or DAC B. Low selects DAC A; high selects DAC B.
Parallel Data Bits 11 Through 0.
Chip Select Input. Active low. Used in conjunction with R/W to load parallel data to the input latch or to read
data from the DAC register. When CS and R/W are held low, the latches are transparent. Any changes on the
data lines are reflected in the relevant DAC output.
Read/Write. When low, used in conjunction with CS to load parallel data. When high, used in conjunction with
CS to read back the contents of the DAC register. When CS and R/W are held low, the latches are transparent.
Any changes on the data lines are reflected in the relevant DAC output.
Positive Power Supply Input. This part can be operated from a supply of 2.5 V to 5.5 V.
