General Description
The LF198/LF298/LF398 are monolithic sample-and-hold circuits which utilize BI-FET 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 low as 6 µs 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 to be included ins...
