When used as an F/V converter, the TC9400 generates
an output voltage linearly proportional to the input
frequency waveform.
Each zero crossing at the threshold detector’s input
causes a precise amount of charge (q = C
to be dispensed into the op amp’s summing junction.
This charge, in turn, flows through the feedback
resistor, generating voltage pulses at the output of the
op amp. A capacitor (C
pulses into a DC voltage, which is linearly proportional
to the input frequency.
