3.2 W into 4 Ω — what that means for the speaker load
The MAX98355BEWL+T delivers 3.2 W continuous into a 4 Ω load from a single supply.
Protection set — depop, short-circuit, thermal shutdown
Depop circuitry suppresses the turn-on/turn-off pop that otherwise needs an external mute transistor or series relay. Short-circuit protection on the output and thermal shutdown cover the common failure modes in a portable product — a crushed speaker wire or a blocked vent. Shutdown pin lets a microcontroller put the amplifier into a near-zero quiescent state when audio is idle.
Sourcing and lifecycle
The MAX98355BEWL+T carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is on record.
