DESCRIPTION
The CAT5269 is two digitally programmable
potentiometers (DPPs) integrated with control logic
and 18 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 CAT5269 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 -40C to 85C industrial
operating temperature range and offered in a 24-lead
SOIC and TSSOP packages.
