In this video, the presenter is going to explain about the instrumentation amplifier with the derivation of the output voltage. And also in this video, it has been explained that how this instrumentation amplifier is superior to the normal...
Here is a simple stereo amplifier you can make with a CD6283 audio amplifier and a few passive components. It provides an output of 4.6 watts per channel with a 12V power supply. Circuit diagram of the stereo amplifier is...
Here is a simple hi-fi audio stereo power amplifier based on TDA2616 IC. This amplifier works on two 12V batteries or one ±12V AC/DC adaptor. The circuit can deliver 2x12-watt output power for 8-ohm loads with ±16V dual-power supply. Circuit...
LM338 voltage regulator can also be used as an audio amplifier. The output voltage can be controlled by varying the IC’s reference voltage (pin 1), which is reflected as the output signal in the speaker. The IC can handle...
Here is how we can build a 5W stereo audio power amplifier based on TEA 2025 IC and two potentiometers for left and right volume controls. Its power output is 2.5W on the left and right channels each with...
Here is a simple 10-watt audio amplifier using IC LM1875. The IC has five pins and can deliver a maximum of 18-watt output power depending upon the supply voltage and load. The author’s prototype is shown in Fig. 1. Circuit...
An “ideal” or perfect operational amplifier is a device with certain special characteristics such as infinite open-loop gain, infinite input resistance, zero output resistance, infinite bandwidth and zero offset. Operational amplifiers are used extensively in signal conditioning or perform...
Use of audio amplifiers is increasing day by day. This project deals with the transmission of the audio signal wirelessly and amplification of the received signal using VTF-108 Bluetooth module and audio amplifier IC TA8210AH. Bluetooth module can connect to...
The TDA2003 is a great sounding low wattage chip amp that's perfect for casual listening with bookshelf and computer speakers. In this video, the presenter is going to show you how to design and build a stereo TDA2003 amplifier. First,...
