Philips Semiconductors Product specification 2 W BTL audio amplifier TDA8543 The voltage loss on the positive supply line is the saturation voltage of a PNP power transistor, on the negative side the saturation voltage of an NPN power transistor. FUNCTIONAL DESCRIPTION The TDA8543(T) is a BTL audio power amplifier capable of delivering an output power between 1 and 2 W, depending on supply voltage, load resistance and package. Using the MODE pin the device can be switched to standby and mute condition.

SOLDERING Introduction Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 °C. There is no soldering method that is ideal for all IC packages.
