LM2902EP

Low Power Quad Operational Amplifiers

General Description

The LM2902 consists of four independent, high gain, inter-

nally 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.

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. For example, the LM2902 can be directly operated

off of the standard +5V power supply voltage which is used

in digital systems and will easily provide the required inter-

supplies.

Unique Characteristics

n

In the linear mode the input common-mode voltage

range includes ground and the output voltage can also

swing to ground, even though operated from only a

single power supply voltage

n

The unity gain cross frequency is temperature

compensated

n

The input bias current is also temperature compensated
