PGA305: Architecture

jw

Part Number: PGA305

Hello, the simplify block diagram shows two ADC's. One for temperature and the other pressure.

Normally I expect a mux connecting  the two inputs to a single ADC. Can you confirm that two different ADC's are used.

Thanks

    Hello JW,

    Yes, there are two separate ADCs used and there is no muxing between them. While they are separate, they are each actually the same architecture of ADC, so they will have the same performance. The main difference is in the analog front end that feeds the inputs to the two ADCs.

    Regards,
