SIMPLIFIED_VOLTAGE－LEVEL_SENSOR

Published:2009/7/9 23:18:00 Author:May | From:SeekIC

This circuit uses only one IC, either 1, LM393 dual comparator or 1/2, LM339 quad comparator. RV1 and RV3 set the full scale reference voltage, and RV2 and RV4 set the switching thresholds to a value between 0 V and the full-scale reference. The change in input voltage needed to fully switch the output state is less than 0.05 mV (typical).
