universal single and dual power supply quad op-amp circuit

LM324 is a high-gain quad op-amp, which has four modules inside. Both single power and dual power supply are available for operating. It can work under a rather wide range of working power supply voltage. A very small Supply Current is needed. Input bias current is with temperature compensation performance, so no external frequency compensation components are needed. Amplifier LM324 can be applied in conversion amplifiers, DC gain units and universal op-amp circuits for many applications. And it also can be used directly as interface circuit for a variety of logic circuits and other low-pressure systems. Direct models or substitutions can be LMl24、CFl24MD、CF224LD、CFl24MJ、CF224LJ、CF324CJ and CF324CP and so on. The circuit shown above is the situation that LM324 is used as a dual-threshold voltage comparator.
