80W Power Amplifier Circuit circuit diagram

80W power amplifier circuit diagram based MJL4281A / MJL4302A and MJE15034 / MJE15035 power transistor. Actually the output power range is about 60W to 80W. This is an incredibly excellent amplifier. It's easy to construct, applies generally offered parts and is stable and well-performing. The diagram featured is really a full update on the original project, and even though it has a lot of similarities, is definitely a different design.

CMoy Headphone Amplifier Circuit

The following diagram is the circuit of CMoy headphone amplifier. Chu Moy designed a very popular headphone amplifier that’s easy to build, and it can be built small enough to fit in a pocket, power supply and all. It’s powerful enough to drive very inefficient headphones to thunderous volumes from even weak sources

The op-amp used for this circuit is OPA2132PA, you may use OPA2132P or OPA2134PA as the alternative op-amp chip.

Multi-color LED Driver Schematic

Multi-color LED Driver Schematic

Have you ever wondered how many various colours can illuminate a LED? One, two or possibly three? Making this simple circuit, you will discover it a lot more. The important component in this design is a dual LED. One such accessory includes two inside the 'slices' of different diode LED, that each and every of them produces a different color (commonly green and red). For the drive needs three pins, a common cathode and two separate roots. In this way every single of the two integrated diodes can light up as independent of one another. You'll find only two colors that may create this dual LED.
