BA4560FV-GE2

Overview

The BA4560FV-GE2 is a low-noise dual-supply operational amplifier manufactured by Rohm Semiconductor. It features two independent circuits in an SSOP-B8 package. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 4 V/µs, and an input offset voltage of 500 µV. The device operates with a supply voltage range of 8 V to 30 V (±4 V to ±15 V). Input bias current is typically 5 nA, while the equivalent input noise voltage is 8 nV/√Hz. It supports a maximum output current of 25 mA per channel and maintains a common-mode rejection ratio of 70 dB.

Feature Summary

• Low noise performance suitable for precision signal amplification
• Wide operating power supply voltage range for flexible system integration
• Built-in phase compensation capacitor simplifies circuit design
• Integrated electrostatic protection circuit enhances component reliability

Applications

• Audio equipment signal processing
• Battery-powered devices requiring low power consumption
• Precision instrumentation circuits
• General-purpose analog signal conditioning

Procurement Notes

Verify the specific suffix -GE2 against the manufacturer's latest documentation to confirm RoHS compliance and pinout compatibility. Confirm that the SSOP-B8 package dimensions match the target PCB footprint requirements. Check for any recent Product Change Notices or End-of-Life announcements from Rohm Semiconductor prior to finalizing procurement plans.

Selection Notes

Select this component when low noise density and wide supply voltage tolerance are required. Ensure the application does not exceed the 4 MHz bandwidth limit or require shutdown functionality. Verify that the 500 µV input offset voltage meets the system's accuracy requirements. Consider thermal dissipation within the SSOP-B8 package if driving high loads near the 25 mA output limit.

Part Context

This part belongs to the BA4560 series of operational amplifiers designed for general-purpose and audio applications. It is distinct from variants like the BA4560F-E2 which may offer different bandwidth characteristics. The -GE2 suffix indicates specific packaging and environmental compliance attributes defined by Rohm Semiconductor for surface-mount assembly.

Replacement Considerations

BA4560YF-MGE2 is listed as a substitute option by the manufacturer.
