LM124 Operational Amplifier

The texts in the PDF file :

The LM124 series 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 range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.


LM124 pinout datasheet


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


1. Eliminates need for dual supplies
2. Four internally compensated op amps in a single package
3. Allows directly sensing near GND and VOUT also goes to GND
4. Compatible with all forms of logic
5. Power drain suitable for battery operation
