LM2904W

Low power dual operational amplifier

Features

■ Internally frequency compensated

■ Large DC voltage gain: 100 dB

■ Wide bandwidth (unity gain): 1.1 MHz

(temperature compensated)

■ Very low supply current/op (500 µA)

■ Low input bias current: 20 nA (temperature

compensated)

■ Low input offset current: 2 nA

■ Input common-mode voltage range includes

negative rail

■ Differential input voltage range equal to the

power supply voltage

■ Large output voltage swing 0V to (VCC

+ - 1.5 V)

■ ESD internal protection: 2 kV

Description

This circuit consists of two independent, high

gain, internally frequency compensated

operational amplifiers, designed specifically for

automotive and industrial control system. It

operates 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

from standard +5 V which is used in logic systems

and will easily provide the required interface

electronics 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.
