Time to recover within rated error band from 160% overdrive.
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.
Hold mode noise is proportional to the length of time a signal is held. For example, if the hold time (t
noise is typically 3 V (150 mV/s x 20 ns). This value must be combined with the track mode noise to obtain total noise.
Total energy of worst case track-to-hold or hold-to-track glitch.
Typical thermal impedances:
Clocked mode is specified with a 50% clock duty cycle.
Analog input voltage should be limited 0.8 volts to maintain device in linear range.
