Philips Semiconductors Product specificiation 3 W BTL mono audio output amplifier with DC volume control TDA7056A The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit.
