The STMicroelectronics low power operational amplifiers consists of two independent, high gain operational amplifiers that have frequency compensation implemented internally. They are designed specifically for automotive and industrial control systems. This circuit operates from a single power supply over a wide range of voltages. The LM2904B is guaranteed up to 36 V supply voltage operation. The low power supply drain is independent of the magnitude of the power supply voltage.

Low input bias current 20 nA
Low input offset current 2 nA
Input common-mode voltage range includes negative rail
Differential input voltage range equal to the power supply voltage
