QUAD OPERATIONAL AMPLIFIERS

LM324

FEATURES

● Internally frequency compensated for unity gain

● Large DC voltage gain : 100dB

● Wide power supply range : 3V~32V(or±1.5V~15V)

● Input common-mode voltage range includes ground

● Power drain suitable for battery operation

ORDERING INFORMATION

QUAD OPERATION AMPLIFIERS

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.
