Hi i need a VTF to convert voltage to Frequency for some testing.
I'm using VFC32

Problem: I have wired exactly the same as the figure 1 but can't get the circuit working.
**broken link removed**
troubleshooting:
1. without any passive component, connect power supply +/-15V, connect Fo to oscilloscope. sinewave of 15Vpp show on scope
2. connect exactly same circuit recommended, weird waveform. not squarewave
PLease help.... Thanks in advance
