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. These 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 7 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.
Read/Write. When low, used in conjunction with CS to load parallel data. When high, used in conjunction
with CS to read back contents of the DAC register.
Positive Power Supply Input. This part can be operated from a supply of 2.5 V to 5.5 V.
