I have an application which requires a PWM output proportional to pressure for which I intend to use the PGA900, with the PWM signal setup on the TOPDIG output pin. Using the EVM this seems to work fine. The application has a supply voltage range of 3.0 - 3.3V, however the PGA900 data sheet gives its supply voltage range as 3.3V to 30V.
Question : as I don't need the analogue backend, is it feasible that the PGA900 can reliably operate down to 3.0V VDD?
Thanks,
