The AD651 is a fast, high-precision single-chip charge-balance analog (voltage or current) to frequency converter. It is synchronous VFC, in that its full-scale output frequency depends on an external clock frequency instead of the usual external capacitor in a one-shot oscillator circuit. Read full article
