FEATURES
Multipower BCD technology Very high operating voltage range (±50 V) DMOS power stage High output power (100 W into 8 Ω @ THD =10%, with VS = ±40 V) Muting and stand-by functions No switch on/off noise Very low distortion Very low noise Short-circuit protected (with no input signal applied) Thermal shutdown Clip detector Modularity (several devices can easily be connected in parallel to drive very low impedances) DESCRIPTION
Thanks to the wide voltage range and to the high output current capability it is able to supply the highest power into both 4-Ω and 8-Ω loads. Parallel mode is possible by connecting several devices and using pin11. High output power can be delivered to very low impedance loads, so optimizing the thermal dissipation of the system Table 1.
