■ VERY LOW NOISE

■ SHORT CIRCUIT PROTECTED (WITH NO

INPUT SIGNAL APPLIED)

■ THERMAL SHUTDOWN

■ CLIP DETECTOR

■ MODULARITY (MORE DEVICES CAN BE

EASILY CONNECTED IN PARALLEL TO

DRIVE VERY LOW IMPEDANCES)

class AB amplifier in Hi-Fi field applications (Home

Stereo, self powered loudspeakers, Top class

TV). Thanks to the wide voltage range and to the

high out current capability it is able to supply the

highest power into both 4Ω and 8Ω loads. The built

in muting function with turn on delay simplifies the

remote operation avoiding switching on-off noises.

Parallel mode is made possible by connecting

more device through of pin11. High output power

can be delivered to very low impedance loads, so

optimizing the thermal dissipation of the system.
