The Newcomer's Forum / Heat from LM386? (noisy cricket)
« on: October 29, 2007, 01:58:50 AM »
Hi, I'm about to embark on my first electronics project more complex than wiring a guitar -- the noisy cricket amp (radioshack version) and I have a question regarding my intended housing for the amp.

I'm planning on squeezing the amp in a very small space, inside a rubber/plastic toy. The datasheet for the LM386 says its operating temp is 70 celcius; should I be allowing "breathing space" around the circuit? If the answer is yes, would adding ventilation holes to the enclosure increase the likelyhood of RF interference? (is RF actually a concern? I honestly have no idea what I'm doing  :duh )
Is a heatsink a good idea considering the limited space the amp will be squeezed into and the fact that summer temps often raise above 35 celcius? Does anyone know of a heatsink that is suitable for an LM386?
