Description

The LM2902B consists of four independent, high gain operational amplifiers (Op

Amps) 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 LM2902B is guaranteed

up to 36 V supply voltage operation. The low power supply 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 can now

be more easily implemented in single power supply systems. For example, these

circuits can be directly supplied from the standard 5 V 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.
