DESCRIPTION

The CAT5133 is a high voltage Digital Programmable

Potentiometer

memory and control logic to operate in a similar

manner to a mechanical potentiometer. The DPP

consists of a series of resistive elements connected

between two externally accessible end points. The tap

points between each resistive element are connected

to the wiper outputs with CMOS switches. A 7-bit

wiper control register (WCR) independently controls

the wiper tap switches for the DPP. Associated with

the control register is a 7-bit nonvolatile memory data

Changing the value of the wiper control register or

storing that value into the nonvolatile memory is

performed via a 3-input Increment-Decrement interface.

The CAT5133 comes with 2 voltage supply inputs: V

(digital supply voltage) input and V+ (analog bias

supply) input. Providing separate Digital and Analog

inputs allow the potentiometer terminals to be as much

as 10 volts above V

The CAT5133 can be used as a potentiometer or as a

two terminal, variable resistor. It is designed for circuit

level or system level adjustments in a wide variety of

applications.

On power-up, the contents of the nonvolatile data

location. The CAT5133 is shipped with the DR

programmed to position 64.
