摘要
设计了基于LF398的采样保持电路,给出了电路中采用的电容、电阻、电位器的典型值;同时对其输出信号的放大保护电路进行了设计,并强调了合理选取补偿电阻、设计分压保护电路和抑制零点漂移三个要点。
The article designs a sampling and holding circuit, and gives the typical value of capacitor, resistor and alterable? resistor in this dissertation. At the same time, it has designed amplifying and protecting circuit for the S/H signal. And three points having been stressed, that is to select properly compensating? resistor, to design safety circuit through the separate resistor voltage and to bate output voltage offset of amplifying circuit.
