BA7786FP-Y

Overview

The BA7786FP-Y is a Class D audio amplifier IC manufactured by ROHM Semiconductor, designed for notebook computer applications. It operates within a supply voltage range of 4.5V to 5.5V, supporting battery-powered and USB-powered systems. The device features a 1-channel mono output configuration compatible with mono and stereo headphones. It integrates a suspend function and dedicated input pins for system beep and power management signals.

Feature Summary

• Class D amplification architecture optimized for efficiency in portable devices
• Integrated suspend mode for power conservation during idle states
• Dedicated inputs for system beep and power management control

Applications

• Notebook computer speaker and headphone amplification
• Battery-powered audio systems
• USB-powered multimedia devices

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's current datasheet to confirm package type and pinout compatibility. Confirm RoHS compliance status as required by your assembly process. Check for obsolete status indicators on distributor platforms, as this part may be discontinued or superseded by newer revisions. Ensure the supplier is an authorized distributor to guarantee component authenticity and traceability.

Selection Notes

Select this component when designing audio stages for notebooks requiring low-power Class D performance. It is suitable for designs needing integrated suspend functionality and direct system beep integration. Consider the 25-HSOP package constraints for PCB layout. Evaluate if the fixed supply voltage range aligns with the target system's power rails before finalizing the design.

Part Context

This component belongs to ROHM's multimedia audio amplifier series specifically engineered for laptop computers. It complements other models like the BA7806FP-E2, which serves as a linear voltage regulator rather than an audio amplifier. The BA7786FP-Y focuses on signal amplification rather than power regulation, addressing distinct functional requirements within portable electronic systems.
