BA8522RF-E2

Overview

The BA8522RF-E2 is a dual general-purpose operational amplifier from ROHM Semiconductor, designed for high-reliability applications. It features a low noise architecture with a gain-bandwidth product of 6 MHz and a slew rate of 3 V/µs. The device operates on split supply voltages ranging from ±2.0 V to ±16.0 V (4 V to 32 V total). Key electrical characteristics include an input offset voltage of 1.5 mV, input bias current of 500 nA, and common-mode rejection ratio of 90 dB. It is housed in an SOP-8 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• High reliability construction with extended operating temperature range up to +105°C
• Internal phase compensation eliminates external component requirements
• Integrated ESD protection providing immunity against human body mode discharge
• Low noise design suitable for sensitive audio signal processing

Applications

• Audio preamplifier circuits
• Signal conditioning stages
• General-purpose analog amplification

Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's latest documentation to confirm environmental compliance status and pinout compatibility. Confirm that the SOP-8 package variant matches the intended PCB footprint. Ensure the supply voltage limits are respected within the specified ±16.0 V split supply constraint during system design validation.

Selection Notes

Select this component when a dual-channel op-amp with low noise performance and wide supply voltage flexibility is required. It serves as a robust alternative to standard general-purpose amplifiers where higher reliability and extended temperature operation are necessary. Consider the 6 MHz bandwidth and 3 V/µs slew rate for moderate-speed signal processing tasks.

Part Context

The BA8522R belongs to ROHM's high-reliability operational amplifier family, which integrates internal ESD protection and wider temperature ranges compared to standard variants. This series is engineered for stability in demanding environments, offering improved durability while maintaining low distortion and noise characteristics typical of professional audio and precision instrumentation applications.
