CAT5411

Dual Digitally Programmable Potentiometers (DPP™) with

64 Taps and SPI Interface

FEATURES

■ Automatic recall of saved wiper settings at

■ Two linear-taper digitally programmable

power up

potentiometers

■ 2.5 to 6.0 volt operation

■ 64 resistor taps per potentiometer

■ 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

■ Industrial temperature ranges

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

■ Potentiometer control and memory access via

SPI interface: Mode (0, 0) and (1, 1)

■ Low wiper resistance, typically 80Ω

■ Nonvolatile memory storage for up to four wiper

settings for each potentiometer

DESCRIPTION

wiper control register or any of the non-volatile data

registers is via a SPI serial bus. 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 register.

The CAT5411 is two Digitally Programmable

Potentiometers (DPPs™) integrated with control logic

and 16 bytes of NVRAM memory. Each DPP consists of

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

The CAT5411 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.
