DAC Current Output.
DAC Analog Ground. This pin should normally be tied to the analog ground of the
system.
Ground Pin.
Parallel Data Bits 7 through 0.
Not internally connected.
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 readback contents of DAC Register.
Positive power supply input. These parts can be operated from a supply of +2.5 V to
+5.5 V.
DAC reference voltage input terminal.
DAC feedback resistor pin. Establish voltage output for the DAC by connecting to
external amplifier output.
