Simple voltage to frequency converter


Posted on Feb 7, 2014

The timer is used in typical configuration, except that the timing resistor is replaced with the current source based on the op-amp DA1 (741). This solution allowed to obtain a good linearity (better than 3%). With the value of components used in this circuit the output frequency will increase linearly from 0 to 21kHz while the input voltage incre

ases from 0 to 5 V (the input voltage controls the output frequency with the relationship 4. 2 kHz/V).
