Note 1. The value of the reference resistor is about 300 Ω. When this circuit is used with (VrefH – VrefL) = 2 V, a current of 6.7 mA will flow. Use an
operational amplifier or emitter follower with at least this current capacity.
2. The analog input impedance is lower for AC inputs. Therefore, an operational amplifier or emitter follower with a high slew rate and a wide
bandwidth must be used in the previous stage output, and the impedance must be reduced to under 100 Ω.
