Description  
Voltage or current input  
• Wide dynamic range  
The RC4152 is a monolithic circuit containing all of the  
active components needed to build a complete voltage-to-  
frequency converter. Circuits that convert a DC voltage to a  
pulse train can be built by adding a few resistors and capaci-  
tors to the internal comparator, one-shot, voltage reference,  
and switched current source. Frequency-to-voltage convert-  
ers (FVCs) and many other signal conditioning circuits are  
also easily created using these converters.  
Applications  
• Precision voltage-to-frequency converters  
• Pulse-width modulators  
• Programmable pulse generators  
• Frequency-to-voltage converters  
• Integrating analog-to-digital converters  
• Long-term analog integrators  
• Signal conversion:  
The RC4151 was the first monolithic VFC available and  
offers guaranteed temperature and accuracy specifications.  
The converter is available in a standard 8-pin plastic DIP.
