LM158/LM258/LM358/LM2904

Low Power Dual Operational Amplifiers

General Description

The LM158 series consists of two independent, high gain,

internally 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 LM158 series can be directly

operated 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 and LM2904 are available in a chip sized pack-

age (8-Bump micro SMD) using National’s micro SMD pack-

age technology.

Unique Characteristics

Voltage Controlled Oscillator (VCO)

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.

The unity gain cross frequency is temperature

compensated.

The input bias current is also temperature compensated.
