  • RE: ADS7953: application diagram for an OPA192

    Resolved
    Hi Chi, That really depends on the source impedance. If the source impedance is very high, then the customer will likely need an OPA at the input of each channel. However, if their source impedance is relatively low, <= 500ohms, then the OPA can sit…
