Broad dynamic pulse width modulator is mainly formed by the integrated timer circuit and integral circuit. As a result of op-amp, the temperature stability is good, linear dynamic range is wide, and the narrowest output pulse is 2μs, the widest pulse is 6ms,the ratio of wide, narrow pulse can reach 300:1. With the change of the modulativon input signal, the corresponding change of output pulse width will happen, resulting in the effect of pulse-width, and it can also output a saw-tooth-wave voltage signal at the same time.
