DRV2511-Q1: Could the analog input be used for current feedback ?

Part Number: DRV2511-Q1

Hi Team,

My customer studies the DRV2511 for a voice coil application, lots of channels are involved. To simplify the system it would be very convenient to used the analog input to have some current feedback.

In fact they want to generate a sinusoidal current of 1kHz at around 3A. The current loop should have F-3dB of about 10kHz and PWM is about 10x higher. It is not clear to me from the DS how the analog input influences the PWM from the functional block diagram in the DS and it not described in detail in text either. Could help me on this please.

Best regards,
