Philips Semiconductors Product specification 12 W car radio power amplifier TDA1020 The TDA1020 is a monolithic integrated 12 W audio amplifier in a 9-lead single in-line (SIL) plastic package. The device is primarily developed as a car radio amplifier. At a supply voltage of V = 14,4 V, an output power of 7 W can be delivered P into a 4 Ω load and 12 W into 2 Ω. To avoid interferences and car ignition signals coming from the supply lines into the IC, frequency limiting is used beyond the audio sp

Philips Semiconductors Product specification 12 W car radio power amplifier TDA1020 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. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief
