AVT1391 A

The system using the integrated transducer f / U type TC9401 allows the frequency to be converted directly into a proportional voltage. The converter can be used to measure the frequency or - after applying a voltage comparator at its output - as a frequency comparator. The kit was designed based on a typical manufacturer's application. The negative voltage necessary for the transmitter operation is obtained by using artificial mass circuits. In this way, the whole can be powered with a single voltage, it is not necessary to use a converter.

The device is especially recommended for the constructors of systems in which frequency conversion to voltage is required

Selected parameters:

• frequency range of the input signal - 0-9 kHz
• maximum input voltage - <9 V (for 15 V supply voltage)
• output voltage range - 0-9 V
• transmitter zeroing circuit
• power supply - 10-15 V
• printed circuit board and documentation included
