AZ4558CMTR-G1

Overview

The AZ4558CMTR-G1 is a dual bipolar operational amplifier manufactured by Diodes Incorporated, utilizing the SOIC-8 surface-mount package. It features internally frequency compensation and high gain characteristics. The device supports a maximum supply voltage of ±18V or a single supply up to 36V. Electrical specifications include a typical large signal voltage gain of 100dB, a gain bandwidth product of 5.5MHz at 10kHz, and an input bias current of 400nA maximum. Operating temperature range spans from -40°C to +85°C.

Feature Summary

• Internally frequency compensated for stability without external components
• High gain and phase match between amplifiers
• Wide operating voltage range supporting dual or single power supplies

Applications

• Audio AC-3 decoder systems
• Audio amplifiers

Procurement Notes

Verify the specific suffix G1 indicates compliance with green packaging standards as defined in the manufacturer's ordering information. Confirm that the CM designation corresponds to the SOIC-8 package type required for the intended circuit layout. Ensure compatibility with the specified -40 to 85°C operating temperature range for the target environment.

Selection Notes

Select this component when a dual operational amplifier with internal frequency compensation is required for general-purpose applications. Consider the SOIC-8 package dimensions for PCB space constraints. Evaluate the 5.5MHz gain bandwidth product against system signal frequencies to ensure adequate performance margins.
