DESCRIPTION
The CAT5259 is four digitally programmable
potentiometers (DPPs) integrated with control logic
and 16 bytes of NVRAM memory. Each 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 separate 8-bit control register
(WCR) independently controls the wiper tap switches for
each DPP. Associated with each wiper control register
are four 8-bit non-volatile memory data registers (DR)
used for storing up to four wiper settings. Writing to the
wiper control register or any of the non-volatile data

registers is via a 2-wire serial bus. On power-up, the
contents of the first data register (DR0) for each of the
four potentiometers is automatically loaded into its
respective wiper control registers.
The CAT5259 can be used as a potentiometer or as a
two terminal, variable resistor. It is intended for circuit
level or system level adjustments in a wide variety of
applications. It is available in the 0C to 70C commercial
and -40C to 85C industrial operating temperature
ranges and offered in a 24-lead SOIC and TSSOP
package.
