4. For hold times longer than 50 ns, the input common mode voltage may affect the hold mode distortion. (This is due to nonlinear
droop that varies with VCM.) For optimal performance, CADEKA recommends that the held output signal be used within 50 ns of the
application of the hold signal.
5. Sampling bandwidth is defined as the -3 dB frequency response of the input sampler to the hold capacitor when operating in the
sampling mode. It is greater than tracking bandwidth because it does not include the bandwidth of the output amplifier.
6. Hold mode noise is proportional to the length of time a signal is held. This value must be combined with the track mode noise to
obtain total noise.
7. Optimized for hold mode performance and low power.
