VFC121 Precision Single Power Supply VOLTAGE-TO-FREQUENCY CONVERTER

The VFC121 is a monolithic voltage-to-frequency converter consisting of an integrating amplifier, voltage reference, and one-shot charge pump circuitry. High-frequency complementary NPN/PNP circuitry is used to implement the charge-balance technique, achieving speed and accuracy far superior to prev.
