  • RE: op AMP matched for the ADC

    Resolved
    Hi Suy, Yes, that is correct, the 54ohm in parallel times 2, is to make the analog impedance 100ohm differential. No need to consider the capacitive term. Your calculation is correct, 200ohms is ideal for the LMH6401 to drive but 160ohms should be fine…
