Dual 256-Tap, Low-Drift,

Digital Potentiometers in 10-µMAX

General Description

Features

The MAX5403/MAX5404/MAX5405 is a family of dual

linear taper digital potentiometers. Each device has one

3-terminal potentiometer and one 2-terminal variable

resistor (Figure 1). The MAX5403/MAX5404/MAX5405

operate from +2.7V to +5.5V single-supply voltages

and use an ultra-low supply current of 0.1µA. These

devices also provide glitchless switching between

resistors taps as well as a convenient power-on reset

(POR) that sets the wiper to the midscale position at

power-up. The potentiometer consists of a fixed resistor

with a wiper contact that is digitally controlled through a

3-wire serial interface and has 256-tap points. It per-

forms the same function as a discrete potentiometer or

variable resistor.

o 10-Pin µMAX Small Footprint Package

o 256-Tap Positions

o Ultra Low 0.1µA Supply Current

o +2.7V to +5.5V Single-Supply Operation

o Low End-To-End Temperature Coefficient:

35ppm/°C

o Low Ratiometric Temperature Coefficient:

5ppm/°C

o Power-On Reset: Wiper Goes to Midscale

(Position 128)

o Glitchless Switching Between Resistor Taps

o 3-Wire SPI™ -Interface Compatible

o 10k /50k /100k Resistor Values

These parts are ideal for applications requiring digitally

controlled resistors. Three resistance values are avail-

able: 10k (MAX5403), 50k (MAX5404), and 100k

(MAX5405). A nominal resistor-temperature coefficient

of 35ppm/°C end-to-end and 5ppm/°C ratiometric make

the MAX5403/MAX5404/MAX5405 ideal for applications

requiring low temperature-coefficient variable resistors,

such as adjustable-gain circuit configurations.

The MAX5403/MAX5404/MAX5405 are available in a 10-

pin µMAX package. Each device is guaranteed over the

extended industrial temperature range (-40°C to +85°C).
