LF398N Monolithic Sample and Hold Circuit IC – DIP-8 Package
The LFx98x devices are monolithic sample-and-hold circuits that use BI-FET technology to obtain ultrahigh DC accuracy with fast signal acquisition and low droop rate. Operating as a unity-gain follower, DC gain accuracy is 0.002% typical, and acquisition time is as low as 6 µs to 0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth. Input offset adjustment is accomplished with a single pin and does not degrade input offset drift. The wide bandwidth allows the LFx98x to be included inside the feedback loop of 1-MHz operational amplifiers without having stability problems. An input impedance of 1010 Ω allows high-source impedances to be used without degrading accuracy.
