Status
Active: In Production.
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 0.1µA 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 position 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 potentiometer or variable resistor.
These parts are ideal for applications requiring digitally controlled resistors. Three resistance values are available: 10kΩ (MAX5413), 50kΩ (MAX5414), and 100kΩ (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).
