The EUA2382 is a high efficiency 2 channel bridged-tiedload (BTL) Class-D audio power amplifier, driving stereospeakers at up to 10W/CH with 6Ω or 8Ω Load.The EUA2382 features a differential input architecture offeringimproved noise immunity over a single-ended (SE) inputamplifier, Amplifier gain is internally configured and canbe ed to 20, 26, 32 or 36dB utilizing the GAIN0 and GAIN1 gain pins.

Advanced EMI Suppression Technology with SpreadSpectrum Control enables the use of inexpensive ferritebead filters at the outputs while meeting EMCrequirements for system cost reduction.

EUA2382 is not only fully protected against shorts and overload, an adjustable power limiter and a DC detection circuit for protection of the connected speakers. The DC detect and Pin-to-Pin, Pin-to-Ground and Pin-to-Power Short Circuit protection circuit protect the speakers from output DC and pin shorts caused in production. The short circuit protection and thermal protection includes an auto recovery feature.

EUA2382 is available in thermally efficient 28-pin TSSOP package and will be able to output full power on a 2-layer PCB.
