10 W Audio Amplifier based TDA 2003

10 W Audio Amplifier based TDA 2003
With only one active integrated circuit TDA 2003 as component this circuit can provide up to 10W of audio power to the load which can be between 2 and 8 ohm. As usual integrated circuit TDA2003, should be placed with which appropriate heat sink to prevent damage to internal components on the temperature of the IC. (more…)

Low Power Amplifier 2×100 mW with TL082

Low Power Amplifier 2×100 mW with TL082
This Low Power Amplifier  2 x 100 mW, without great pretensions, is simple to assemble, and works with a single power supply 9V battery (for example). However, it works a little better with a supply voltage slightly higher, +12 V to +18 V. The Low Power Amplifier  2 x 100 mW circuit is based on the combination of op amp and an output stage push-pull with two transistors to charge more than a few mA and assuring to have
