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.

FEATURES

•Operates from ±5V to ±18V supplies

•Hold leakage current 6pA @ TJ= 25°C

•Less than 4µs acquisition time

•TTL, PMOS, CMOS compatible logic input

•0.5mV typical hold step at CH=0.01µF

•Low input offset: 1MV (typical)

•0.002 gain accuracy with RL=2kΩ

•Low output noise in hold mode

•Input characteristics do not change during hold mode

•High supply rejection ratio in sample or hold

•Wide bandwidth
