Dear Sir,
We are required to drive two PZT with positive voltage only polarity (0V to around 30V). As we prefer to use only one chip, could you comment in possibility to use the differential amplifier of DRV8662 as two separate amplifiers? We are thinking to connect in+ to signal for PZT1 and in- to signal for PZT2. The out+ will be connected to one terminal of PZT1 and out- to one terminal of PZT2. The other terminal of PZT1 and PZT2 will be connected to ground. Would this scheme work?
Thank you for your kind attention.
Kind regards,
Anindito
