DESCRIPTION
The CAT5401 is four Digitally Programmable
Potentiometers (DPPs) integrated with control logic
and 16 bytes of NVRAM memory. Each DPP consists of
a series of 63 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 6-bit control register
(WCR) independently controls the wiper tap switches for
each DPP. Associated with each wiper control register
are four 6-bit non-volatile memory data registers (DR)
used for storing up to four wiper settings. Writing to the
CAT5401

wiper control register or any of the non-volatile data
registers is via a SPI 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 register.
The CAT5401 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.
