Philips Semiconductors Product specification 2 × 1 W BTL audio amplifier TDA8542 PINNING FUNCTIONAL DESCRIPTION SYMBOL PIN The TDA8542(T) is a 2 × 1 W BTL audio power amplifier capable of delivering 2 × 1 W output power to an 8 Ω load at THD = 10% using a 5 V power supply. Using the MODE pin the device can be switched to standby and mute condition. The device is protected by an internal thermal shutdown protection mechanism.

Philips Semiconductors Product specification 2 × 1 W BTL audio amplifier TDA8542 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. SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board.
