Maxim Integrated MAX5414EUD T

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.
