PKD01AY

单片峰值检波器与复位和保持模式 Monolithic Peak Detector with Reset-and-Hold Mode

GENERAL DESCRIPTION

The PKD01 tracks an analog input signal until a maximum amplitude is reached. The maximum value is then retained as a peak voltage on a hold capacitor. Being a monolithic circuit, the PKD01 offers significant performance and package density advantages over hybrid modules and discrete designs without sacrificing system versatility. The matching characteristics attained in a monolithic circuit provide inherent advantages when charge injection and droop rate error reduction are primary goals.
