The LM2904PT is a low-power high gain dual Operational Amplifier which employs internal frequency compensation. The circuit operates from a single power supply over a wide range of voltages. The low power supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifier, DC gain blocks and all the conventional op amp circuits which can now be more easily implemented in single power supply systems. For example, this circuit can be directly supplied from the standard 5V which is used in logic systems and easily provides the required electronic interfaces without requiring any additional power supply. In linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from a single power supply.
Very low supply current/amplifier, essentially independent of supply voltage
Input common-mode voltage range includes negative rail
Differential input voltage range equal to the power supply voltage
100dB Large DC voltage gain
20nA (temperature compensated) Low input bias current
