Sample-and-hold amplifier
NE/SE5537
DESCRIPTION
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 circuit shown in Figure 1 contains two operational
amplifiers which function as a unity gain amplifier in the sample mode.
The first amplifier has bipolar input transistors which give the system a low offset
voltage.
The second amplifier has JFET input transistors to achie...
