The module must be mounted on a large, high-efficiency aluminum heatsink.

Maximum supply voltage is typically around ±40V .

Always implement a (usually involving a relay) between the IC output and the speakers. If the STK411-210E fails, it often shorts Vcccap V sub c c end-sub

Operating beyond these limits will likely result in immediate failure of the IC. Typically around ±50V to ±54V (No signal). Thermal Resistance ( θj−ctheta sub j minus c end-sub
