Wiring circuit

Build a Voltage-To-Frequency Converter Circuit Diagram 2. Using a Burr-Brown VFC 32 IC, this voltage-to-frequency converter uses few components. The schema values are shown in the figure. This charge-balanced V/F converter uses a VFC32 or a VFC320 IC. 

The positive charge from the 1-mA balances the negative charge from the input. V/F converter waveforms are shown in Fig. 100-l(b).
