Status
Active: In Production.
Description
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 performs
the same function as a discrete potentiometer or
variable resistor.
These parts are ideal for applications requiring digitally
controlled resistors. Three resistance values are available:
10kΩ (MAX5403),
50kΩ (MAX5404), and
100kΩ
(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).
