If the Voltage onthe non inverting input is higher, then the internal outputtransistor is off and the output will be high. If the Voltage onthe inverting input is higher, then the output transistor willbe on and the output will be low. The LMV331 /393/339 hasan open drain output stage, so a pull up resistor to a positivesupply Voltage is required for the output to switch size of the pull up resistor is recommended to bebetween 1 kW and 10 kW. This range of values will balancetwo key factors; , power dissipation and drive capabilityfor interface 19 illustrates the basic operation of a comparatorand assumes dual supplies.
9 The comparator compares theinput Voltage (VIN) on the non inverting input to thereference Voltage (VREF) on the inverting input. If VIN is lessthan VREF, the output Voltage (VO) will be low. If VIN isgreater than VREF, then VO will be 19. + + kVO+VINV+0 VVREFVOUTVINTimeV+ comparators and StabilityA common problem with comparators is oscillation due totheir high gain. The basic comparator configuration inFigure 19 may oscillate if the differential Voltage betweenthe input pins is close to the device s offset Voltage . This canhappen if the input signal is moving slowly through thecomparator s switching threshold or if unused channels areconnected to the same potential for termination of unusedchannels. One way to eliminate output oscillations or chatter is to include external hysteresis in the Configuration with HysteresisAn inverting comparator with hysteresis is shown inFigure 20.

When VIN isgreater than the Voltage at V+, then the output will be hysteresis band (Figure 21) created from the resistornetwork is defined as:DV)+VT1*VT2where VT1 and VT2 are the lower and upper trip points, 21. VT1 is calculated by assuming that the output of thecomparator is pulled up to supply when high. Theresistances R1 and R3 can be viewed as being in parallelwhich is in series with R2 (Figure 22). Therefore VT1 is:VT1+VCCR2 R1 R3 )R2VT2 is calculated by assuming that the output of thecomparator is at ground potential when low. The resistancesR2 and R3 can be viewed as being in parallel which is inseries with R1 (Figure 23). Therefore VT2 is:VT2+VCC R2 R3 R1) R2 R3 LMV331 , NCV331, LMV393, HIGH+VCCR3VT1R1R2 Figure 22.
