5.5 W mono into 8 Ω — the LM384N/NOPB in a through-hole audio chain
The Texas Instruments LM384N/NOPB is a Class AB mono audio amplifier delivering 5.5 W into an 8 Ω load from a 12 V to 26 V supply rail.
Class AB topology and built-in protection
On-chip short-circuit and thermal protection means the output stage folds back current during a speaker-wire short and shuts down if the die exceeds the safe junction temperature — no external crowbar or fuse is needed for fault tolerance in a single-supply audio design.
