We're using 3 of the TSC2011 amps to measure currents from our 3-phase H-bridge FETs to a 28VDC brushless DC motor. When driving the PWM out, we're seeing 100-300mV DC offsets on the TSC2011 Vout, making them inaccurate. Is this expected?

Is this due to noise, common mode voltage, or the PWM edges? Any recommendations to improve the circuit?
