Description of product

MAX40056 Bidirectional Current Sense Amplifiers

Maxim Integrated MAX40056 Bidirectional Current Sense Amplifiers offer an input common-mode range that extends from -0.1V to +65V combined with protection against negative inductive kickback voltages to -5V. The MAX40056 Amplifiers are ideal for phase current monitoring of inductive loads where pulse width modulation is used to control the drive voltage and current. The MAX40056 implements an advanced technique to help reject common-mode input PWM edges with slew rates up to and beyond ±500V/µs. The device provides a common mode rejection ratio (CMRR) of typically 60dB (50V, ±500V/µs input) and 140dB DC.
