BA4560RFV-E2

Overview

The BA4560RFV-E2 is a low noise dual operational amplifier manufactured by ROHM Semiconductor. It features two independent circuits housed in an SSOP-8 surface-mount package. The device operates within a supply voltage range of 8 V to 30 V and supports dual supplies from 4 V to 15 V. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 4 V/µs, and an input offset voltage maximum of 500 µV. Input bias current is specified at 50 nA, with a typical channel operating current of 3 mA. The component provides a minimum common-mode rejection ratio of 70 dB and an input voltage noise density of 8 nV/sqrt Hz. It functions without a shutdown mode and operates across a temperature range of -40°C to +105°C.

Feature Summary

• Low noise performance suitable for precision signal conditioning applications
• Dual circuit configuration providing two independent amplifiers in a single package
• Wide supply voltage operation supporting both single and dual power rails
• Extended industrial temperature range capability

Applications

• Precision sensor signal amplification
• Audio pre-amplifier stages
• Instrumentation front-end circuits
• Active filter implementations

Procurement Notes

Verify the specific package variant, as the BA4560RFV-E2 designation corresponds to the SSOP-8 form factor. Confirm RoHS compliance status and check for end-of-life notifications, as related family members have received discontinuation notices. Ensure design-in compatibility with the required thermal and electrical specifications before finalizing procurement plans.

Selection Notes

Select this component when low input voltage noise is critical for maintaining signal integrity in high-gain stages. The 4 MHz bandwidth and 4 V/µs slew rate define its frequency response limits. Compare against higher-speed alternatives if bandwidth requirements exceed 4 MHz or if lower quiescent current is necessary for battery-powered designs.

Part Context

This part belongs to the BA4560 series of low noise operational amplifiers produced by ROHM Semiconductor. The series includes variants with different packages such as SOP-J and TSSOP-B8. The RFV suffix specifically denotes the SSOP-8 package type. The device is designed for general-purpose analog signal processing where noise performance is a primary constraint.

Replacement Considerations

BA4560YFVM-MGTR is listed as a substitute option.
