LMV761, LMV762 www.ti.com SNOS998H – FEBRUARY 2002 – REVISED MARCH 2013 APPLICATION INFORMATION BASIC COMPARATOR A basic comparator circuit is used to convert analog input signals to digital output signals. The comparator compares an input voltage (VIN) at the non-inverting input to the reference voltage (VREF) at the inverting pin. If VIN is less than VREF the output (VO) is low (VOL). However, if VIN is greater than VREF, the output voltage (VO) is high (VOH). V VREF - VIN + + VO V - Figure 24.

This allows very high resistance circuits to be used without any concern for matching input resistances. This also allows the use of very small capacitors in R-C type timing circuits. This reduces the cost of the capacitors and amount of board space used.
