应用功能： 单片采样保持电路 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 ms to 0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth.
