BA4560RFJ-GE2

Overview

The BA4560RFJ-GE2 is a dual-channel general-purpose operational amplifier manufactured by Rohm Semiconductor. It features a gain-bandwidth product of 4 MHz and a slew rate of 4 V/µs. The device operates within a supply voltage range of 8 V to 30 V, with a typical supply current of 3 mA. Key electrical specifications include an input offset voltage of 500 µV, an input bias current of 50 nA, and a common-mode rejection ratio of 70 dB. It supports an output current of 25 mA per channel and functions across a temperature range of -40°C to 105°C in an 8-SOP-J surface-mount package.

Feature Summary

• Dual-channel architecture providing two independent amplification circuits within a single compact package.
• Low noise performance characterized by low equivalent input noise voltage density for signal integrity.
• Wide operating temperature range suitable for industrial and commercial environments.
• High common-mode rejection ratio ensuring accurate differential signal processing.

Applications

• Industrial signal conditioning
• Audio pre-amplification stages
• Sensor interface circuits

Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as End-of-Life (EOL) with obsolescence scheduled for April 25, 2025. Confirm RoHS3 compliance and check for specific packaging variants such as tape-and-reel or cut-tape options. Ensure design-in decisions account for the discontinuation timeline to avoid future supply chain disruptions.

Selection Notes

Select this component when a dual op-amp with moderate bandwidth and low noise is required. Compare against the BA4558RFJ-GE2 if lower bandwidth suffices, or consider the BA4560F-E2 for different thermal characteristics. Verify that the 8-SOP-J package dimensions fit the target PCB layout constraints and that the 30 V maximum supply voltage aligns with system power rails.

Part Context

This component belongs to the BA4560 series of low-noise operational amplifiers from Rohm Semiconductor. It is designed as a successor or variant to standard dual op-amps, offering improved noise performance while maintaining compatibility with common pinouts. The series targets applications requiring precision analog signal processing in space-constrained designs.

Replacement Considerations

BA4560YF-MGE2 is identified as a substitute part number by the manufacturer.
