EUA2380 ds2380 ver1.0 oct. 2016 1 10-w inductor free stereo audio amplifier with low emi description the EUA2380 is a high efficiency 2 channel bridged- tied load (btl) class-d audio power amplifier, driving s tereo speakers at up to 10w/ch with 6 or 8 load. the EUA2380 features a differential input architecture offering improved noise immunity over a single-ended (se) in put amplifier. advanced emi suppression technology with spread spectrum control enables the use of inexpensive fer rite 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 dete ction circuit for protection of the connected speakers. t he dc detect and pin-to-pin, pin-to-ground and pin-to-pow er short circuit protection circuit protect the speake rs 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. features wide supply voltage: 4.5v to 14.5v enhanced modulation scheme reduces emi emission 10-w/ch into an 6- load from a 12-v supply 10-w/ch into an 8- load from a 13-v supply differential inputs or single-ended input speaker protection circuitry 26-db fixed gain power limit function thermal and short-circuit protection 28-pin tssop package with thermal pad rohs compliant and 100% lead(pb)-free halogen-free applications televisions usb speaker mini speaker consumer audio equipment typical application circuit figure1. simplified application schematic
