AD5424
Description
DAC Current Output.
DAC Analog Ground. This pin should normally be tied to the analog ground of the system.
Ground.
Parallel Data Bits 7 to 0.
No Internal Connection.
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. 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 Terminal.
DAC Feedback Resistor Pin. Establish voltage output for the DAC by connecting to external amplifier
output.
