BD8820MUV-E2

Overview

The BD8820MUV-E2 is a Class D audio amplifier IC manufactured by ROHM Semiconductor. It features a stereo output configuration designed for driving stereo headphones. The device operates within a power supply voltage range of 2.4 V to 5.5 V. Key electrical specifications include a maximum output power of 80 mW per channel into a 16 Ω load and 60 mW per channel into a 32 Ω load. The unit exhibits a total harmonic distortion plus noise (THD+N) of 0.006% at 16 Ω and a signal-to-noise ratio of 101 dB. It utilizes a VQFN-16 package with dimensions of 3.0 mm x 3.0 mm.

Feature Summary

• Stereo Class D audio amplification architecture
• Low total harmonic distortion plus noise performance
• High signal-to-noise ratio specification
• Virtual ground operation capability

Applications

• Stereo headphone driver circuits
• Portable audio devices requiring low power consumption
• Mobile communication handsets
• Digital audio players

Procurement Notes

Verify the specific suffix E2 indicates RoHS compliance when sourcing. Confirm the VQFN-16 package variant matches the design footprint. Check for moisture sensitivity levels if storage conditions exceed factory limits. Ensure the operating temperature range of -40°C to +85°C aligns with the target environment requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring high-fidelity stereo audio reproduction in compact form factors. The low THD+N and high SNR make it suitable for sensitive listening devices. Consider the 2.4 V minimum supply voltage for battery-operated systems. The virtual ground feature simplifies single-supply circuit designs compared to dual-supply alternatives.

Part Context

This part belongs to ROHM's Class D audio amplifier portfolio, specifically optimized for mobile and portable electronics. It integrates protection circuits typical of modern audio ICs. The VQFN-16 package allows for space-constrained PCB layouts. It serves as a solution for upgrading from linear amplifiers or lower-performance switching amplifiers in consumer audio hardware.

Replacement Considerations
