Voltage / frequency conversion circuit composed of TA7505

Published:2011/7/7 6:13:00 Author:Lucas | Keyword: Voltage conversion , frequency conversion | From:SeekIC

The circuit is composed of the ramp generator, Miller integration circuit, voltage comparator, etc., and it can switch 0-10V input voltage into the corresponding 0-100HZ output frequency. Circuit's switching frequency is determined by the Al ramp generator, and the conversion error is mainly caused by the integrator reset time, dielectric absorption of integration capacitor. In order to reduce errors caused by the reset time, the output of the comparator is connected the trigger composed of TC4013.
