Converters: Voltage to Frequency

0.02%  Volt / F Converter Consumes only 26 �A: 07/04/96 EDN-Design Ideas

10 kHz VFC uses Charge Pump Variation: 04/09/98 EDN-Design Ideas

DPP Adds Versatility to VFC: 11/14/02  EDN-Design Ideas  / The basic VFC (voltage-to-frequency converter) comprises an integrator (IC1) and a Schmitt-trigger circuit (IC2). The integrator converts the dc input voltage, VIN, to a linear voltage ramp, and the Schmitt trigger sets the limits of the integrators output voltage.
