Forum Post: DRV2667 full scale peak voltage
Hi, Let me confirm about below. Can user output desired peak-to-peak voltage in case of digital playback (I2C input)? According to datasheet, it seems that output peak-to-peak voltage is fixed. For...

Hi Machida, Yes, the gain is fixed for those values during digital playback. If you need other OUT +/- values, you might want to consider using an analog input signal. In this case, the gain is set as:...
