LF398 Datasheet (NXP) - Sample-and-hold amplifiers

LF398, Sample-and-hold amplifiers

The LF198/LF298/LF398 are monolithic sample-and-hold circuits which utilize high-voltage ion-implant JFET technology to obtain ultra-high DC accuracy with fast acquisition of signal and low droop rate.

Operating as a unity gain follower, DC gain accuracy is 0.002% typical and acquisition time is as
