BA4560RF-E2

Overview

The BA4560RF-E2 is a dual low-noise operational amplifier manufactured by ROHM Semiconductor. It features a gain-bandwidth product of 4 MHz and a typical slew rate of 4 V/µs. The device operates within a supply voltage range of 8 V to 30 V, with a maximum dual supply of ±15 V. Key electrical parameters include an input offset voltage of 500 µV, input bias current of 5 nA, and input noise voltage density of 8 nV/√Hz. It provides a common-mode rejection ratio of 70 dB and functions across a temperature range of -40°C to +105°C in an SOP-8 package.

Feature Summary

• Low noise performance with 8 nV/√Hz input voltage noise density
• Wide operating temperature range from -40°C to +105°C
• High gain bandwidth product of 4 MHz for signal integrity
• Integrated phase compensation capacitor for stability

Applications

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS compliance status. Check for End-of-Life notices or Product Change Notifications as availability may be restricted. Ensure the SOP-8 package dimensions match the target PCB footprint before finalizing procurement decisions.

Selection Notes

Select this component when low noise and wide bandwidth are critical requirements. The 4 MHz gain-bandwidth product supports higher frequency applications compared to standard audio op-amps. Consider the 500 µV input offset voltage for precision DC applications. Verify that the 8 V minimum supply voltage aligns with the system power rails.
