The LM224J is a quad low power high-gain internally frequency compensated Operational Amplifier designed 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. Application areas include transducer amplifiers, DC gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems.
Internally frequency compensated for unity gain
Very low supply current drain (700µA) - Essentially independent of supply voltage
Input common-mode voltage range includes ground
Differential input voltage range equal to the power supply voltage
Allows direct sensing near GND and VOUT also goes to GND
Compatible with all forms of logic
Power drain suitable for battery operation
In the linear mode the input common-mode, voltage range includes ground and the output voltage
Can swing to ground, even though operated from only a single power supply voltage
Unity gain cross frequency is temperature compensated
Input bias current is also temperature compensated
100dB Large DC voltage gain
45nA Low input biasing current (temperature compensated)
