CAT5133
16 Volt Digital
Potentiometer (POT) with
128 Taps and an Increment
Decrement Interface
Description
The CAT5133 is a high voltage digital POT integrated with
EEPROM memory and control logic to operate in a similar manner to
a mechanical potentiometer. The digital ponentiometer 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 digital potentiometer. 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.
