AD652 Monolithic Synchronous Voltage-to-Frequency Converter

The AD652 synchronous voltage-to-frequency converter (SVFC) is a powerful building block for precision analog-todigital conversion, offering typical nonlinearity of 0.002% (0.005% maximum) at a 100 kHz output frequency. The inherent monotonicity of the transfer function and wide range of clock frequ.
