Overview
The BD88415GUL-E2 is a stereo headphone amplifier manufactured by ROHM Semiconductor. It operates in Class-B topology with an analog input type and supports a supply voltage range of 2.4 V to 5.5 V. The device delivers 80 mW of output power per channel into a 16-ohm load, achieving a total harmonic distortion plus noise (THD+N) of 0.006%. Key electrical parameters include a quiescent current of 2 mA, a slew rate of 0.15 V/µs, and an input offset voltage of 500 µV. It functions within a temperature range of -40°C to +85°C and utilizes a VCSP50L2-14 surface-mount package.
Feature Summary
- Coupling capacitorless design eliminates the need for large external output capacitors.
- Integrated shutdown function reduces standby current consumption significantly.
- Low total harmonic distortion plus noise ensures high-fidelity audio reproduction.
Applications
- Portable audio devices requiring low-power stereo amplification
- Mobile phones and smartphones with limited board space
- MP3 players and digital audio players
Procurement Notes
Verify the specific suffix E2 indicates RoHS compliance when sourcing. Confirm the VCSP50L2-14 package dimensions match your PCB footprint requirements. Ensure the design supports the 2.4 V minimum operating voltage for battery-powered applications. Check that the thermal management strategy accommodates the specified power dissipation in the small outline package.
Selection Notes
Select this component for designs prioritizing minimal external component count due to its capacitorless architecture. It is suitable for systems requiring low quiescent current to extend battery life. The low THD+N specification makes it appropriate for high-quality audio paths. Verify that the 16-ohm load impedance aligns with the connected headphones or speakers for optimal power delivery.
Part Context
This part belongs to the BD88415GUL series of audio amplifiers from ROHM Semiconductor. It is categorized under Headphone Amplifiers within the broader Audio ICs product line. The device is designed for portable electronics where size and power efficiency are critical constraints.
Replacement Considerations
The BD88410GUL-E2 and BD88420GUL-E2 are documented substitutes within the same family. These alternatives share similar specifications and packaging but may have minor differences in gain configuration or status. Verify pin compatibility and electrical parameters before substitution.
