• Single-ended input, referenced to ground

• V-F or F-V conversion

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.
