General Description
The MAX5413/MAX5414/MAX5415 is a family of dual
linear taper digital potentiometers. Each device has two
3-terminal potentiometers. The MAX5413/MAX5414/
MAX5415 operate from +2.7V to +5.5V single-supply
voltages and use an ultra-low 0.1A supply current.
These devices also provide glitchless switching
between resistor taps, as well as a convenient power-
on reset (POR) that sets the wiper to the midscale posi-
tion at power-up. Each 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 potentiome-
ter or variable resistor.
These parts are ideal for applications requiring digitally
controlled resistors. Three resistance values are avail-
able: 10k
(MAX5413), 50k (MAX5414), and 100k
(MAX5415). A nominal resistor temperature coefficient
of 35ppm/°C end-to-end and 5ppm/°C ratiometric make
the MAX5413/MAX5414/MAX5415 ideal for applications
requiring low temperature-coefficient variable resistors,
such as adjustable-gain circuit configurations.
The MAX5413/MAX5414/MAX5415 are available in a 14-
pin TSSOP package. Each device is guaranteed over the
extended industrial temperature range (-40°C to +85°C).
