Description
DAC Current Output.
DAC Analog Ground. This pin should normally be tied to the analog ground of the system.
Ground.
Parallel Data Bits 9 to 0.
Not Internally Connected.
Chip Select Input. Active low. Use in conjunction with R/
read data from the DAC register. Rising edge of
Read/Write. When low, used in conjunction with
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 Terminal.
DAC Feedback Resistor Pin. Establish voltage output for the DAC by connecting to external amplifier output.
The exposed pad should be connected to ground.
