Tool/software:
Hello,
I'm having problems with one of your devices (DRV8662EVM). According to the datasheet, in section 3.3.3 External Analog Input Mode, a series of changes are required if you use an external analog source (sine wave).
I made these changes using option B. It doesn't work. I've attached the image below.
I've attached the image of the waveform outputting from the source and the waveform input to the EXTIN+ and EXTIN- inputs.( 5V - 10kHz)
I've attached the image of the waveform outputting from the DRV8662's OUT.
It doesn't amplify the input signal; it even decreases it.
I hope you can help me.
Regards,
