BA4558FV-GE2

Overview

The BA4558FV-GE2 is a dual operational amplifier manufactured by ROHM Semiconductor, featuring low noise and wide supply voltage capabilities. It operates within a power supply range of ±4.0 V to ±15.0 V (single supply 8 V to 30 V). Key electrical parameters include a gain-bandwidth product of 2 MHz, a slew rate of 1 V/µs, and an input offset voltage maximum of 6 mV. The device draws a typical current of 1.5 mA per channel and offers an input bias current of 60 nA. It provides high voltage gain with a typical value of 100 dB and maintains an output current capability of 10 mA.

Feature Summary

• Integrated phase compensation capacitor eliminates external frequency compensation requirements.
• Built-in electrostatic protection circuit ensures robustness against human body model discharge.
• Wide operating temperature range supports functionality from -40°C to +105°C.
• Latch-up free design enhances reliability under varying load conditions.

Applications

• Audio signal processing circuits requiring low distortion
• General-purpose analog signal amplification
• Instrumentation amplifier front ends

Procurement Notes

Verify the specific package variant, as the BA4558FV series includes SSOP-B8 configurations. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory updates may affect production batches. Check for end-of-life notifications or obsolescence notices prior to finalizing procurement plans to ensure long-term supply stability.

Selection Notes

Select this component when a dual op-amp with low noise characteristics and wide supply voltage tolerance is required. The integrated phase compensation simplifies layout compared to uncompensated devices. Ensure the application does not require shutdown functionality, as this model lacks that feature. Verify thermal management needs given the specified operating temperature limits.

Part Context

This part belongs to the BA4558 family of dual operational amplifiers designed for general-purpose and audio applications. It serves as a low-noise alternative to standard dual op-amps, offering improved performance in sensitive analog circuits while maintaining compatibility with common pinouts found in similar industry-standard packages.
