The NTE7243 is a voltage−to−frequency converter ideally suited for use in simple low−cost circuits for analog−to−digital conversion, precision frequency−to−voltage conversion, long−term integration, linear frequency modulation or demodulation, and many other functions. The output when used as a voltage−to−frequency converter is a pulse train at a frequency precisely proportional to the applied input voltage. Thus, it provides all the inherent advantages of the voltage−to−frequency conversion techniques, and is easy to apply in all standard voltage−to−frequency converter applications.

Further, the NTE7243 attains a new high level of accuracy versus temperature which could only be attained with expensive voltage−to−frequency modules. Additionally the NTE7243 is ideally suited for use in digital systems at low power supply voltages and can provide low−cost analog−to−digital conversion in microprocessor−controlled systems. And, the frequency from a battery−powered voltage−to−frequency converter can be easily channeled through a simple photo isolator to provide isolation against high common−mode levels.
