Power amplifier modules dissipate significant heat. The datasheet provides thermal resistance figures (junction-to-case, case-to-ambient) and maximum junction temperatures. Practical considerations:
: Typically around 0.4% or lower under nominal operating conditions. Power Supply : Dual (split) power supply configuration (+Vcc / -Vcc). Load Impedance : Standard 6Ω to 8Ω speaker loads. 3. Operational Characteristics Thermal Protection
Designed for long-term use under recommended voltage and thermal conditions; overheating is a common sign of overuse or insufficient cooling. Typical Applications:
