AD5445 PIN FUNCTION DESCRIPTION

Function

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.

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.
