LM158/LM258/LM358/LM2904

Low Power Dual Operational Amplifiers

General Description

The LM158 series consists of two independent, high gain, in-

ternally 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 sys-

tems. For example, the LM158 series can be directly oper-

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

used in digital systems and will easily provide the required

interface electronics without requiring the additional

power supplies.

The LM358 is also available in a chip sized package

(8-Bump micro SMD) using National’s micro SMD package

technology.

Unique Characteristics

n In the linear mode the input common-mode voltage

n The unity gain cross frequency is temperature

n The input bias current is also temperature compensated.

Connection Diagrams

range includes ground and the output voltage can also

swing to ground, even though operated from only a

single power supply voltage.
