4x15W quad amplifier 12V by TA8215

These chips can deliver 15 Watt RMS per channel, into 4 Ohm loudspeakers. That’s more than enough even for loud home use. The peak power current consumption, when saturating all four channels at the same time, would be 12A, which gives good chances that the computer won’t reset from power supply shutdown in such a situation! When using 8 Ohm speakers, the output power and the current consumption are cut down to one half. In fact, that’s my situation, because my present speakers are 8 Ohm.
The amplifier has a typical distortion in the neighborhood of 0.04%. That’s good enough, in my opinion, for a computer sound system, while surely with discrete parts I could have obtained even lower distortion. The gain delivered by the TA8215 is a whopping 50dB, which is MUCH more than needed. So I had to include an attenuator at the input, in order to be able to use the full dynamic range of the sound card.

Circuit Main Amp BCL 6w With LM380

Today we come to see Bridge Amplifier very small-sized about 6Watt only. This work uses the integrated circuit number LM380 then build easy and economize good. When a friend uses 8ohm loudspeakers. Will have the electric power about 6Watt that Voltage Supply 15V or 12Volt all right. Caution be don’t give late a loudspeaker touches Ground may make LM380 can be damaged. As a result request friends have fun Main Bridge amp miniature this size please sir.
