3-channel 80 Watt audio amplifier circuit diagram

This is simple project of  3 Watt Stereo Amplifier Circuit Diagram . This circuit using MAX 7910 IC. The MAX9710 a stereo audio power amplifier IC capable of delivering 3Watts of out put to 4 Ohm loads. MAX9710 can be operated from a single 4.5V to 5.5V power supply , makes it ideal for hand held applications.The IC for  3 Watt stereo amplifier circuit  also features thermal overload protection.  3 Watt Stereo Amplifier Circuit Diagram This 3 Watt stereo amplifier circuit is suitable for small power audio devices such as radio sets and portable CD players. 5 V DC power supply is used for powering the 3 Watt stereo amplifier circuit. 6V battery with an IN 4007 diode series to the positive terminal of it can also be used instead of 5 V DC supply. The 3 Watt stereo amplifier circuit will get a supply voltage approximately 5 V after 0.7 V voltage drop across diode.

This design is inspired by the Minty Boost but it fixes some of the issues that I had with it. The Minty Boost is limited to 600mA due to the LT1302 chip. The Super Boost uses the LM2700 which can push up to 3.6A. This will enable i-devices to draw up to there maximum of 1A which will enable a faster recharge. [ ]

2.4GHz WiFi & ISM Band Scanner. Description and Schematic - Part 1 2.4GHz WiFi & ISM Band Scanner. Firmware and Sowtware - Part 2   Assembly Because the circuit was so simple I took the easy way out and assembled it on a piece of veroboard. Nowadays I would design my own printed circuit board (see custom PCBs). Rather than finding a connector for the Cypress module I simply soldered single core hookup wire directly to the connector pins. This supported the module and allowed me to position it away from the microcontroller to minimise interference. The USB cable was made from a standard USB cable with type A and B connectors, I just cut off the B connector and soldered the wires directly to the veroboard with half an inch of heatshrink tubing to keep it neat. That left the type A connector at the other end, ready to plug into the computer. Note that the red and black wires in the USB cable are +5V and ground respectively. You should check these with a multimeter before so...

This is very simple electronic circuit diagram for 3 to 12 volts converter, this circuit simple and high efficiency step-up dc dc converter circuit that require few external components can be designed using the LM2700 step-up DC/DC converter with a 3.6A, 80mohms internal switch and pin selectable operating frequency. 3 to 12 Volts Converter Circuit Diagram:   With the ability to produce 500mA at 8V from a single Lithium Ion battery, the LM2700 is an ideal part for biasing LCD displays. The LM2700 can be operated at switching frequencies of 600kHz and 1.25MHz allowing for easy filtering and low noise. An external compensation pin gives the user flexibility in setting frequency compensation, which makes possible the use of small, low ESR ceramic capacitors at the output. This circuit can be used for handheld devices and some other portable applications. This step-up DC DC converter will provide a 12 volts DC output voltage from an input voltage range between 2.5 to 4.2volts.

Inductorless 3-to-5 Volts Converter Circuit Diagram. By configuring a comparator and a transistor to control the oscillator in a charge pump circuit, you enable the pump to generate a regulated output of in principle any desired value. Charge pump ICs can either invert or double an input voltage (for example, 3 V to –3 V or 3 V to 6 V). The charge pump itself does not regulate the output voltage and one running off 3 V is not normally capable of generating intermediate output voltage levels like 5 V. However, by adding a comparator and a reference device, you can create arbitrary output levels like 5 V and regulate them as well. Inductorless 3-to-5 Volts Converter Circuit Diagram Charge pump IC1 (a MAX660) has an internal oscillator whose 45 kHz operation transfers charge from C1 to C2, causing the regulated output to rise. When the feedback voltage (pin 3 of IC2) exceeds 1.18 V, the output of comparator IC2 (a MAX921) goes high, turning off the oscillator via T1. The comparator hyste...
