Device Structure

The LM358A-SR is an integrated circuit containing two independent op-amps. It is built using CMOS process technology and housed in an industry-standard SOIC-8 surface-mount package.

Performance Characteristics

Dual amplifier channels improve design flexibility

Low input bias current (600pA) means less signal distortion

High CMRR (120dB) allows accurate signal processing

Fast slew rate (500V/ms) provides rapid response to input changes

Low noise density (70nV/√Hz@1kHz) helps in sensitive signal applications

Stable operation from 3V to 36V single supply

Small input offset voltage (7mV typical)

Application Environments

Suitable for:

Industrial signal processing

Data acquisition systems

Sensor amplification

Low-power and battery-powered equipment

Measurement and control equipment

General-purpose electronic circuits

Selection Guidelines

Choose LM358A-SR if you need:

Dual independent op amps

Operation over a wide supply range (3V~36V)

High immunity to common mode noise

Low power and low input bias current

Surface mount application (SOIC-8 package)

Usage Considerations

Make sure supply voltage does not exceed 36V

Use in environments within -40℃ to +125℃ temperature range

Properly decouple supply pins to reduce noise

Match input characteristics with the signal source for optimal accuracy

Implement correct PCB layout practices to minimize interference
