Product details

Class D stereo amplifier for compact audio systems

The BD28412MUV-E2: The BD28412MUV-: The ROHM BD28412MUV- is a Class D stereo audio amplifier delivering 9W per channel into an 8Ω load from a 4.5V to 13V supply. The 32-VFQFN Exposed Pad package (VQFN032V5050) keeps the footprint small for space-constrained designs like soundbars, portable speakers, and automotive aftermarket audio modules.

The 9W x 2 @ 8Ω rating defines the continuous output power per channel before clipping, assuming adequate supply voltage and heatsinking via the exposed pad. For a 4Ω load, expect roughly half the power (around 5W per channel) due to current limits — plan the speaker impedance accordingly. The 4.5V minimum supply allows operation from a single lithium-ion cell or a 5V rail, while the 13V maximum covers 12V automotive rails with margin.

ROHS3 compliant.

Surface-mount in VQFN032V5050.
