DESCRIPTION
The CAT5133 is a high voltage Digital Programmable
Potentiometer
(DPP)
integrated
with
E2PROM
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
register (DR) used for storing the wiper settings.
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: VCC
(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 VCC and 16 volts above ground.
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
register (DR) are transferred to the wiper control
register (WCR) and the wiper is positioned to that
location. The CAT5133 is shipped with the DR
programmed to position 64.
