Figure 64. Half-Wave Rectifier with Input Current Protection (RI)
Figure 65. Half-Wave Rectifier Waveform
The circuit in Figure 64 uses a single supply to half wave rectify a sinusoid centered about ground. RI limits
current into the amplifier caused by the input voltage exceeding the supply voltage. Full wave rectification is
provided by the circuit in Figure 66.
