LM324 IC - Low Power Quad Op-Amp IC

LM324 is a 14pin IC consisting of four independent operational amplifiers (op-amps) compensated in a single package. Op-amps are high gain electronic voltage amplifier with a differential input and, usually, a single-ended output. The output voltage is many times higher than the voltage difference between the input terminals of an op-amp. These op-amps are operated by a single power supply LM324 and need for a dual supply is eliminated. They can be used as amplifiers, comparators, oscillators, rectifiers, etc. The conventional op-amp applications can be more easily implemented with LM324.

Unique Characteristics

• In the linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage.
• The unity gain cross frequency is temperature compensated.
• The input bias current is also temperature compensated Advantages.
• Eliminates the need for dual supplies.
• Four internally compensated op amps in a single package.
• Allows directly sensing near GND and VOUT also goes to GND.
• Compatible with all forms of logic.
• Power drain suitable for battery operation.

Features:

• Internally frequency compensated for unity gain
• Large DC voltage gain 100 dB
• Wide bandwidth (unity gain) 1 MHz (temperature compensated)
• Wide power supply range:
•         Single supply 3V to 32V
•         dual supplies ±1.5V to ±16V
• Very low supply current drain (700 µA) —essentially independent of supply voltage
• Low input biasing current 45 nA (temperature compensated)
• Low input offset voltage 2 mV and offset current: 5 nA
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply voltage
• Large output voltage swing
