Hi , I found a lot of PKD01 application. Does any new part that can replace this one ?
PKD01
Obsolete
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....

Kevin,
There is no replacement. With fast ADCs, some customers digitize the waveform and
then find the peak with software. Or they build their own with fast op amps and diodes, etc.
