Circuit converts pulse width to voltage

  
The circuit in Figure 1 converts pulse information to a clean dc voltage by the end of a single incoming pulse. In another technique, an RC filter can convert a PWM signal to an averaged dc voltage, but this method is slow in responding. Converting low-duty-cycle pulse information is slower yet.
Circuit converts pulse width to voltage - schematic

The circuit in Figure 1 uses two low-input-biascurrent LT1880 op amps, IC2 and IC3, and an LTC202 quad analog switch, IC1A, IC1B, IC1C, and IC1D, to configure the integrator and sampleand- hold stages that convert a single pulse to a dc voltage. Th
