10-W Inductor Free Stereo Audio Amplifier with Low EMI


The EUA2380 is a high efficiency 2 channel bridged-tied load (BTL) Class-D audio power amplifier, driving stereo speakers at up to 10W/CH with 6Ω or 8Ω Load. The EUA2380 features a differential input architecture offering improved noise immunity over a single-ended (SE) input amplifier.

Advanced EMI Suppression Technology with Spread Spectrum Control enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction.

EUA2380 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.

EUA2380 is available in thermally efficient 28-pin TSSOP package and will be able to output full power on a 2-layer PCB.
