Select a CSA for 12V brush motor in-line current sense

Other Parts Discussed in Thread: INA282, LMP8601

Hi Team,

My customer is using AD8207 in their 12V brush motor applicaiton as a in-line current sensing amplifier, the value of shunt resistor is 3m or 1m ohm, the current is about 35A, the driving PWM frequency is 20kHz. would you please suggest if we have suitable part to compete with AD8207?

I have looked into INA282 and LMP8601/2, looks like INA282's BW and CM step reponse is bad and not suitable although it is P2P with AD8207. And LMP8601/2 seems suitable for this application.
