VFC121 Overview
The VFC121 is a monolithic voltage-to-frequency converter consisting of an integrating amplifier, voltage reference, and one-shot charge pump circuitry. High-frequency plementary NPN/PNP circuitry is used to implement the charge-balance technique, achieving speed and accuracy far superior to previous single power supply VFCs. The high-impedance input accepts signals from ground potential to VS 2.5V.
