　MC33071P Application Field and Working Principle

Introduction:
The MC33071P is a dual general-purpose operational amplifier designed for single-supply systems or battery-operated equipment. The MC33071P has a single-ended output that can be operated down to ground, allowing flexible choice of biasing. The return to zero function of MC33071P can create an SBWG waveform of equal positive and negative symmetry to the core signal, and this waveform can be power-supplied or energy-supplied.
