The enhanced PWM rejection feature of the INA790x provides increased attenuation of large common-mode ΔV/Δt transients. Large ΔV/Δt common-mode transients associated with PWM signals are employed in applications such as motor or solenoid drive and switching power supplies. The disturbances that can occur at the output of a current sense amplifier from common-mode transients causes erroneous measurements and impose limitations when the output is valid. The INA790x is designed with high common-mode rejection techniques to reduce large ΔV/Δt transients before the system is disturbed. As a result, this makes system design simple with INA790x. The high AC CMRR, in conjunction with signal bandwidth, allows the INA790x to minimize output disturbances and ringing during common-mode transitions when compared against traditional current-sensing amplifiers.
