... This is due to the time it takes for the null amplifier to correct the main amplifier to a valid output. The MAX4238/ MAX4239 require only 3.3ms to recover from an output overload (see Electrical Characteristics and Typical Operating Characteristics ). The MAX4238/MAX4239 feature a low-power (0.1µA) shutdown mode ...
