Hi Experts,

do we specify a 3db input bandwidth for this part? we do not find this in the datasheet.

Thanks.

    Hi Simon,

    The sampling bandwidth of the ADC is 40MHz (typical). This is not directly mentioned in the data sheet but can be computed using the analog inputs diagram that shows 150Ω switch impedance (ADC only) and 12pF sampling capacitor. As the ADC has a MUX as well, there will be 2x the R (150Ω + 150Ω).
