DESCRIPTION
DAC current output.
DAC analog ground. This pin is normally tied to the analog ground of the system.
Ground pin.
Parallel data bits 11 to 0.
Chip select input. Active low. Used in conjunction with R/W to load parallel data to the input
latch or read data from the DAC register. Rising edge of CS loads data.
Read/Write. When low, use in conjunction with CS to load parallel data. When high, use with
CS to read back 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.
DAC feedback resistor pin. Establish voltage output for the DAC by connecting to external
amplifier output.
