PKD01  
GENERAL DESCRIPTION  
RST  
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.

INDETERMINATE  
The output buffer amplifier features an FET input stage to  
reduce droop rate error during lengthy peak hold periods. A bias  
current cancellation circuit minimizes droop error at high ambi-  
ent temperatures.  
Innovative design techniques maximize the advantages of mono-  
lithic technology. Transconductance (gm) amplifiers were chosen  
over conventional voltage amplifier circuit building blocks. The  
gm amplifiers simplify internal frequency compensation, minimize  
acquisition time and maximize circuit accuracy. Their outputs  
are easily switched by low glitch current steering circuits. The  
steered outputs are clamped to reduce charge injection errors  
upon entering the hold mode or exiting the reset mode. The inher-  
ently low zero-scale error is further reduced by active Zener-Zap  
trimming to optimize overall accuracy.  
Through the DET control pin, new peaks may either be detected  
or ignored. Detected peaks are presented as positive output  
levels. Positive or negative peaks may be detected without  
additional active circuits, since Amplifier A can operate as an  
inverting or noninverting gain stage.  
An uncommitted comparator provides many application options.  
Status indication and logic shaping/shifting are typical examples.
