LM386 Utility Amplifier

It’s always handy to have a little amp kicking around to trace audio signals, test mics, CD tape and TV audio outputs. You know, something that doesn’t weigh a lot and isn’t clumsy. There are tons of uses for this little circuit. There are a couple of versions of this amplifier chip. Both are 8 […]

Battery Powered Amplifier

This is battery powered amplifier based on LM386 chip and has an input buffer that is feeding the inverting input. The input buffer helps to retain treble details going into the LM386 chip. It is powered from a single 9V battery. The architecture of the amplifier has been updated with an input buffer feeding the […]

68W LM3886 Amplifier

LM3886 is a high-fidelity audio power amplifier IC capable of delivering 68W of continuous power using 4 Ohm speakers. LM3886 provides excellent S/N ratio of 92dB and above as well as extremely low total harmonic distortion over the audio spectrum. LM3886 comes equipped with Self Peak Instantaneous Temperature Protection Circuitry (SPiKE) that makes it a […]

60W Power Amplifier

This is a simple and low cost 60W power amplifier. The optimal supply voltage is around 50V, but this amp can work from 30 to 60V. The maximum input voltage is around 0.8 – 1V. As you can see, in this design the components have a big tolerance, so you can build it with almost […]

Headphone Amplifier Module

140mW into 32 Ohm loads, Ultra-low Distortion Those wanting private listening to their music program should add this Headphone Amplifier to the Modular Preamplifier chain. The circuit was kept as simple as possible compatibly with a High Quality performance. This goal was achieved by using two NE5532 Op-Amps in a circuit where IC1B is the […]
