As a V\/F converter, it transforms an analog input voltage into a proportional output frequency with linearity error as low as 0.07% at 100kHz full scale. As an F\/V converter, it performs the inverse function. The device can operate at full-scale frequencies up to 1MHz and accepts both unipolar (0-10V) and bipolar (\u00b110V) input ranges. The open-collector frequency output is compatible with TTL, CMOS, and optocoupler inputs, making it ideal for applications requiring galvanic isolation or long-distance analog signal transmission over digital links.","working_principle":"The AD650 operates using a charge-balance architecture for V\/F conversion. (1) In V\/F mode, the input voltage drives a current (proportional to VIN) into the integrator op-amp, which produces a ramping output voltage. When the integrator output crosses the comparator threshold, a one-shot timer is triggered, activating the precision current source that discharges the integrator by a fixed amount of charge. The one-shot duration is precisely controlled by an external capacitor. (2) The output pulse frequency is proportional to the input voltage because the rate at which charge-balancing pulses occur equals the rate at which input current charges the integrator. Each output pulse removes a fixed quantum of charge (IREF x tOS), so the pulse frequency FOUT = VIN \/ (IREF x tOS x RIN). (3) In F\/V mode, the input frequency triggers the one-shot timer, which generates fixed-width current pulses that are integrated by an external RC network to produce a DC output voltage proportional to the input frequency.","pin_description":"
