BA4580RFJ-GE2

Overview

The BA4580RFJ-GE2 is a dual operational amplifier manufactured by ROHM Semiconductor, housed in an 8-SOP-J surface-mount package. It features a gain-bandwidth product of 10 MHz and a slew rate of 5 V/µs. The device operates within a supply voltage range of 4 V to 32 V, with a maximum dual supply of ±16 V. Key electrical specifications include a maximum input offset voltage of 300 µV, an input bias current of 100 nA, and an input voltage noise density of 5 nV/√Hz. It supports a continuous output current of 50 mA per channel and maintains operation across a temperature range of -40°C to +105°C.

Feature Summary

• Low noise performance with high open-loop voltage gain for precision signal conditioning
• Wide single or dual power supply voltage capability for flexible system integration
• Built-in phase compensation capacitors eliminate the need for external frequency stabilization components
• Robust protection features including electrostatic discharge circuits and latch-up immunity

Applications

• Precision audio pre-amplifiers and signal processing stages
• Industrial sensor signal amplification and conditioning
• Active filter circuits requiring low distortion and wide bandwidth
• Instrumentation amplifier front-ends for measurement systems

Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS3 compliance and check for specific tape-and-reel packaging requirements. Ensure design compatibility with existing SOP-J8 footprints and validate thermal management strategies for the specified operating temperature range before finalizing procurement plans.

Selection Notes

Select this component when low input offset voltage and low noise are critical for maintaining signal integrity in dual-channel applications. The wide supply voltage range accommodates both single-supply and split-rail architectures. Consider the 50 mA output drive capability for direct interfacing with moderate load impedances without additional buffering stages.

Part Context

This part belongs to the BA4580 series of general-purpose operational amplifiers from ROHM Semiconductor. The series is characterized by bipolar input stages offering high gain and low noise. The BA4580 family provides a cost-effective solution for standard analog signal processing tasks where moderate speed and precision are required.
