MAX40056UAUA/V+ Maxim Integrated, Current Sense Amplifier Differential 8-Pin ÎMAX

The Maxim Integrated Products MAX40056 is a bidirectional current-sense amplifier with an input common-mode range that extends from -0.1V to +65V together with protection against negative inductive kickback voltages to -5V. This CSA is well-suited for phase current monitoring of inductive loads, such as motors and solenoids, where pulse width modulation is used to control the drive voltage and current. The MAX40056 uses an improved technique to help reject common-mode input PWM edges with slew rates up to and beyond ±500V/μs. Common mode rejection ratio (CMRR) is typically 60dB (50V, ±500V/μs input) and 140dB DC, typical.60dB AC CMRR Rejection at 50V, ±500V/μs PWM Edges Multiple Gain Options 10V/V, 20V/V, 50V/V Internal, 1% Reference for Bidirectional Offset
