Frequently Asked Questions
What is the output power of the LM4780 in stereo and mono modes?
The LM4780 delivers 60W per channel in stereo mode and up to 120W in bridged mono (BTL) configuration when driving an 8-ohm load. This makes it suitable for high-power home audio and multimedia systems where either stereo or high-power mono output is needed from a single IC.
What protection features does the LM4780 include?
The LM4780 integrates thermal shutdown protection to prevent damage from overheating, along with short-circuit protection on the output to guard against accidental speaker short events. These features allow the amplifier to recover safely without permanent damage, improving system reliability in consumer and professional audio designs.
What package does the LM4780 use and how is it mounted?
The LM4780 is housed in a Transistor Outline Vertical (TO-220 style) through-hole package, which provides excellent thermal conductivity when mounted to a heatsink. This package is ideal for high-power audio amplifier designs where significant heat dissipation is required to maintain safe junction temperatures at full output power.
What applications is the LM4780 best suited for?
The LM4780 is ideal for home theater amplifiers, hi-fi stereo receivers, multimedia speaker systems, musical instrument amplifiers, and any application requiring 60W per channel stereo or 120W bridged mono audio power output. Its mute pin and protection features simplify design in consumer electronics and professional audio equipment.
