Product Summary
The NE5537 monolithic sample-and-hold amplifier combines the best features of ion-implanted JFETs with bipolar devices to obtain high accuracy, fast acquisition time, and low droop rate. This device is pin-compatible with the LF198, and features superior performance in droop rate and output drive capability. The differential logic threshold is 1.4V with the sample mode occurring when the logic input is high. It is available in 8-lead TO-5, 8-pin plastic DIP packages, and 14-pin SO packages.
