LM158-LM258-LM358

LM158A-LM258A-LM358A

Low Power Dual Operational Amplifiers

■ Internally frequency compensated

■ Large DC voltage gain: 100dB

■ Wide bandwidth (unity gain): 1.1mHz

(temperature compensated)

■ Very low supply current/op (500µA) essentially

independent of supply voltage

■ Low input bias current: 20nA

(temperature compensated)

■ Low input offset voltage: 2mV

■ Low input offset current: 2nA

■ Input common-mode voltage range includes

ground

■ Differential input voltage range equal to the

power supply voltage

■ Large output voltage swing 0V to (Vcc - 1.5V)

Description

These circuits consist of two independent, high-

gain, internally frequency-compensated which

were designed specifically to operate from a

single power supply over a wide range of voltages.

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

now

can

be

more

easily

implemented in single power supply systems. For

example, these circuits can be directly supplied

with the standard +5V which is used in logic

systems and will easily provide the required

interface

electronics

without

requiring

any

additional power supply.

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.
