Tool/software:
I am working on a project utilizing the DRV2605L and would like to drive the IN/TRIG pin with and audio signal that is 400mV p-p.
If I understand correctly, the data sheet documentation describes a method to modify the ATH_MAX_INPUT parameter showing its default value at 255 (hex: 0xFF) for a default input voltage of 1.8V p-p.
Table 16 in section 7.16.13 shows what appears to be a formula for this ATH_MAX_INPUT Voltage (VPP) = ATH_MAX_INPUT[7:0] × 1.8 V / 255 but its application isn't clear.
Does this suggest, for example that the DRV2605L would accept at 0.9V p-p signal on the IN/TRIG pin if the default hex value of 0xFF (255) were changed to 0x1FE, essentially dividing the value in half?
Otherwise, would you please be able to tell me how is this accomplished?
Any and all help is very much appreciated and thank you!
