DESCRIPTION
The CAT5409 is four 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
four potentiometers is automatically loaded into its
respective wiper control register (WCR).
The Write Protection (
WP
) pin protects against
inadvertent programming of the data register.
The CAT5409 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.
