Here is a simple stereo audio amplifier that can be made using a TDA1517 IC. A 14.4V regulated voltage is used as power supply for this amplifier. TDA1517 is a 9-pin (single-in-line package) audio amplifier IC, which is inexpensive...
This simple stereo audio amplifier is based on a 12-pin TA8207K IC, which is inexpensive and easily available. In addition, it requires only a few resistors and electrolytic and ceramic capacitors. You can get output power of about 4.6W...
This article covers the major differences between isolated amplifier-based and isolated modulator-based solutions, and explains their uses in improving the overall efficiency and power throughput in various industrial and automotive applications. Industrial applications such as motor drives, photovoltaic inverters, and...
Here is a simple project of a 6W+6W stereo amplifier using a 14-pin LA4440 IC. This amplifier can deliver an output power of 6W on a 4-ohm speaker (6W each on the left and right channels). The amplifier operates...
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...
