DESCRIPTION
The CAT5419 is two Digitally Programmable
Potentiometers (DPP) integrated with control logic
and 16 bytes of NVRAM memory.
A separate 6-bit control register (WCR) independently
controls the wiper tap position 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 wiper control register
or any of the non-volatile data registers is via a 2-wire
serial bus (I

C-like). On power-up, the contents of the

first data register (DR0) for each of the two potentiometers
is automatically loaded into its respective wiper control
registers (WCR).
The Write Protection (
WP
) pin protects against
inadvertent programming of the data register.
The CAT5419 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.
