The BD5426EFS-E2: The BD5426EFS-: The BD5426EFS- is a ROHM Class D stereo amplifier rated for 10W per channel into an 8Ω load. That 10W x 2 figure is the headline spec: it tells you the amplifier can drive a typical bookshelf or mid-range speaker pair at moderate listening levels without clipping. The 10V to 16.5V supply range means this is a 12V-rail part — think automotive audio, powered speakers, or industrial sound systems — not a 5V or 3.3V portable design.
Package and thermal: the exposed pad is not optional
At 10W per channel into 8Ω, the pad needs a solid thermal via array to the ground plane.
Protection features: depop, mute, short-circuit, thermal
Built-in depop circuitry suppresses the turn-on thump that otherwise couples into the speakers. The mute function lets the system hold the outputs quiet during power-up sequencing or channel switching. Short-circuit and thermal protection are standard for a Class D amp in this power class — they prevent latch-up or damage if the speaker wires short or the heatsink is undersized.
The BD5426EFS- carries an active product status.
