BA5416

Overview

The BA5416 is a dual power amplifier IC from ROHM designed for audio applications. It operates on a supply voltage range of 5.0V to 15.0V and delivers up to 2.5W output power into a 4Ω load at 9V with 10% THD, or 5.4W into a 3Ω load at 12V. The device features a built-in standby switch, thermal shutdown protection, and soft clipping capabilities. It utilizes an SIP-M12 package.

Feature Summary

• Built-in standby switch function allows low-current power control without affecting circuit characteristics.
• Integrated thermal shutout circuit prevents damage during short circuits or insufficient heat dissipation.
• Soft clipping feature minimizes distortion during high-level signal peaks.
• Low switching noise generation during power-on and power-off sequences.

Applications

• Radio cassette players
• Audio amplification systems requiring dual channel output

Procurement Notes

Verify the specific package type upon ordering, as the datasheet indicates the BA5416 uses a cost-reduced package compared to the BA5415A. Confirm that the application design adheres to the recommended operating voltage limits of 15.0V maximum for this specific model variant.

Selection Notes

Select the BA5416 when a cost-effective solution is required for dual-channel audio amplification. Ensure the design accommodates its 5.0V to 15.0V supply range and utilizes the internal standby pin for efficient power management in portable devices.

Part Context

The BA5416 belongs to the BA5415A/BA5416 series of high-output dual power amplifiers manufactured by ROHM. It shares core electrical characteristics with the BA5415A but differs primarily in packaging to offer a lower-cost option while maintaining similar performance metrics for audio applications.

Replacement Considerations

The BA5415A is a direct functional equivalent within the same series. Verify if the specific package difference (cost-reduced vs standard) impacts the mechanical fit and thermal requirements of the target PCB layout.

FAQ

What is the maximum supply voltage for the BA5416?

The maximum recommended operating supply voltage for the BA5416 is 15.0V.

Does the BA5416 require an external heatsink?

The datasheet does not explicitly state that a heatsink is unnecessary for the BA5416 under all conditions, unlike the BA5415A which specifies no heatsink is needed at 9V with RL ≥ 4Ω. Thermal analysis based on the provided dissipation curves is recommended.
