High output power : P O = 10 + 10 W@RL = 2Ω, d = 10% ; PO = 20W@RL = 4Ω , d = 1 %.
High reliabilityof the chip and package with additional complete safety during operation thanks to protection against : .
OUTPUT DC AND AC SHORT CIRCUIT TO GROUND .
OVERRATING CHIP TEMPERATURE .
LOAD DUMP VOLTAGE SURGE .
FORTUITOUS OPEN GROUND .
VERY INDUCTIVE LOADS
Flexibilityin use : bridge or stereo boosteramplifiers with or without boostrapand with programmable gain and bandwidth. Space and cost saving : very low number of external components, very simple mounting system with no electrical isolation between the package and the heatsink (one screw only). In addition, the circuit offers loudspeaker protection during short circuit for one wire to ground
