Product Overview

The LF398AN/NOPB is a monolithic Sample-and-Hold Circuit for use with synchronous correlators. The monolithic sample-and-hold circuit use BI-FET technology to obtain ultrahigh DC accuracy with fast acquisition of signal and low droop rate. Operating as unity-gain follower, DC gain accuracy is 0.002% typical and acquisition time is as low as 6µs to 0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth. Input offset adjust is accomplished with a single pin and does not degrade input offset drift. The wide bandwidth allows the LF198-N to be included inside the feedback loop of 1MHz operational amplifiers without having stability problems. P-channel junction FETs are combined with bipolar devices in the output amplifier to give droop rates as low as 5mV/minute with a 1µF hold capacitor.
