CAT5409

Quad Digitally Programmable Potentiometers (DPP™) with 64 Taps and

2-wire Interface

FEATURES

■ Recall of saved wiper settings at power-up

■ 2.5 to 6.0 volt operation

■ Four linear-taper digital potentiometers

■ 64 resistor taps per potentiometer

■ End-to-end resistance 2.5kΩ, 10kΩ, 50kΩ or 100kΩ

■ 2-wire interface (I²C like)

■ Standby current less than 1µA

■ 1,000,000 nonvolatile WRITE cycles

■ 100 year nonvolatile memory data retention

■ 24-lead SOIC, 24-lead TSSOP and BGA

■ Write protection for data register

■ Low wiper resistance, typically 80Ω

■ Four non-volatile wiper settings for each

potentiometer

DESCRIPTION

The CAT5409 is four Digitally Programmable

Potentiometers (DPP™) integrated with control logic

and 16 bytes of NVRAM memory.

contents of the first data register (DR0) for each of the

four potentiometers is automatically loaded into its

respective wiper control register (WCR).

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 (I²C-like). On power-up, the

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.
