Can MAX9736A accept DC analog input signal and amplify this signal to DC output? Some TI class-D amplifiers, such as TPA3130D2, have DC protection and cannot accept DC input.
But there is no description about DC input protection in ADI MAX9736A datasheet. And what is the production cycle of MAX9736A?
Hi Yulin,
Though there is no description about DC input protection in datasheet, there is relevant message about the input capacitor. We can infer that MAX9736 needs external Cin and Rin to filter out the DC bias. If you want it to accept DC input, just neglect the external high-pass filter.
Nevertheless, we don't recommend you use DC input since the characteristics in datasheet are measured from 22 Hz to 22 kHz. DC performance is not guaranteed.
