CAT5409
Quad Digital
Potentiometer (POT)
with 64 Taps
and I2C Interface
Description
The CAT5409 is four digital POTs 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 digital POT. 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 I2C 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 (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.
