CAT5133/D
CAT5133
16 Volt Digitally Program-
mable Potentiometer (DPP)
with 128 Taps and an
Increment Decrement
Interface
Description
The CAT5133 is a high voltage Digital Programmable
Potentiometer (DPP) integrated with EEPROM 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: V
CC
(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
CC
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.
