3 features: this small amplifier is constructed with the tda2616 ic, with a maximum supply capability of 2 x 15wrms (4ohm) of 2 x 10wrms (8ohm). The ic is thermally and short-circuit protected. Additional rectifier and smoothing filter are unnecessary, as alternating current can be directly connecte...
4 assembly hints 1. Assembly (skipping this can lead to troubles ! ) ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 make sure you have the right tools: • a good quality soldering iron (25-40w) with a small tip. • wipe it often on a ...
5 assembly hints 1.3 soldering hints : 1- mount the component against the pcb surface and carefully solder the leads 2- make sure the solder joints are cone-shaped and shiny 3- trim excess leads as close as possible to the solder joint remove them from the tape one at a time ! Do not blindly follow ...

7 construction ic1 : tda2616 mount the ic with the metal back pointing at the edge of the circuit board. Mount it sufficiently high, so that the pins do not need to be pruned. Then mount the ic against the heatsink, as indicated in the diagram 1.0. The insulation (covered on both sides with some op-...
8 connection 8. Connection fig. 2.0 make the connections as indicated in figure 2.0 & fig 3.0. Watch the polarity of the loudspeakers. If a ring-core transformer is used, it is possible that the ov (gnd) connection consists of two leads. Finish all connec- tions before switching on the power..
