BA4558RFV-E2

Overview

The BA4558RFV-E2 is a dual operational amplifier manufactured by ROHM Semiconductor, designed for low-noise applications. It features two independent circuits within an 8-pin SSOP package. Key electrical specifications include a gain-bandwidth product of 2 MHz and a slew rate of 1 V/µs. The device operates on a supply voltage range from 8 V to 30 V, with a typical quiescent current of 3 mA per channel. Input characteristics specify a maximum input offset voltage of 500 µV and a bias current of 60 nA. The unit supports an operating temperature range from -40°C to +105°C.

Feature Summary

Low noise performance suitable for sensitive signal processing
Dual circuit configuration in a compact surface-mount package
Wide single or dual power supply operation capability

Applications

Audio pre-amplifier stages
Sensor signal conditioning
Instrumentation amplifiers

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm RoHS compliance and material declarations. Confirm the package type matches the design requirements, as variations exist within the BA4558 family. Check for end-of-life notices or production change notifications prior to finalizing procurement plans.

Selection Notes

Select this component when low input noise voltage density is critical for the application. Ensure the required bandwidth does not exceed 2 MHz. Verify that the supply voltage constraints fit within the 8 V to 30 V range. Consider the thermal management capabilities of the SSOP-8 package for the expected operating environment.

Part Context

This part belongs to the BA4558 series of dual operational amplifiers. It is distinct from other variants like the BA4558RFJ-GE2 which may use different packaging such as SOP-8. The RFV designation specifically indicates the SSOP-8 package format. This series is positioned for general-purpose low-noise analog signal processing tasks.
