STMicroelectronics 

LM2904, LM2904A

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/amplifier, essentially

independent of supply voltage

■ 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 0 V to (VCC+ -1.5 V)

Description

This circuit consists of two independent, high

gain, internally frequency-compensated

operational amplifiers designed specifically for

automotive and industrial control systems. 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 can now be more easily

implemented in single power supply systems. For

example, these circuits can be directly supplied

from the standard +5 V which is used in logic

systems and easily provides 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 a single power supply.
