DESCRIPTION
The CAT5132 is a high voltage Digitally Programmable
Potentiometer (DPP) integrated with EEPROM memory
and control logic to operate in a similar manner as 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 output with
CMOS switches. A separate 7-bit 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
wiper settings. Writing to the wiper control register or the
nonvolatile data register is via a 2-wire serial bus (I
2
C-
like).
On power-up, WCR is set to mid scale (1000000) and
after the Power Supply becomes stable, the contents of
the data register (DR) are transferred to the wiper control
register (WCR) and the wiper is positioned to that
location.
The CAT5132 comes with 2 voltage supply inputs: V
CC
,
the digital supply voltage input and V+, an analog supply
voltage input. These inputs allow the V+ to be as much
as 10 volts higher than the V
CC
and allow the DPP
terminal values to be as much as 15 volts above ground.
The CAT5132 can be used as a potentiometer or as a
two-terminal variable resistor. It is intended for circuit
level adjustments. It is supplied standard in the -40
°
C to
+85
°
C industrial operating temperature range and offered
in the 10-pin MSOP package.
