ADS7953: ads7953

Part Number: ADS7953
Other Parts Discussed in Thread: OPA192

How much is the Rd of the  analog switch of the ads7953?
  • Hello
    In the application section, there are different scenarios for input signal impedance, this might help; what is the concern for the Rd of the mux?
    When connected to the mux, Rd can be estimated to be 200ohms

    Regards
    Cynthia
  • Thank you for your reply.

    There is no description of  Mux's Rd in the datasheet. In my application, an LPF is connected behind MXO, so Mux's Rd is what I want to know.

  • This is not explicitly stated in the datasheet, this is a shortcoming
    Within the Application section 9 of the datasheet, specifically 9.2.2 OPA192 Buffered Multiplexer output might prove helpful for your application
