Package

LM324 is consists of four independent, high gain, internally frequency compensated operational amplifiers
which were designed specifically to operate from a single power supply over a wide voltage range.
Operation from split power supplies is also possible so long as the difference between the two supplies
is 3 volts to 32 volts voltage.
Application areas include transducer amplifier, DC gain blocks and all the conventional OP amp circuits
which now can be easily implemented in single power supply systems.
