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 achieve low leakage current
from the hold capacitor. A unique circuit design for leakage current
cancellation using current mirrors gives the NE5537 a low droop
rate at higher temperature. The output stage has the capability to
drive a 2k load. The logic input is compatible with TTL, PMOS or
CMOS logic. 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.
