How the Circuit Works The IC OPA541 from Burr-Brown is a power opamp is specially designed to work from power supplies […]
How to Design MOSFET Power Amplifier Circuits – Parameters Explained
In this post I have explained various parameters that must be considered while designing a MOSFET power amplifier circuit. We also analyze the difference between bipolar junction transistors (BJT) and MOSFET characteristics and understand why MOSFETS are more suitable and efficient for power amplifier applications. Contributed by Daniel Schultz Overview When designing a power amplifier […]
Types of Power Amplifier Classes Explained in Simple Words
In this post I am going to explain power amplifiers and their classification according to their output electrical characters and application. We will be exploring amplifier classes: A, B, AB, C, D, E, F, G, H, I, S and T briefly and yes, that’s a lot of amplifier types that are available in today’s electrical […]
100 Watt Power Amplifier Circuit Diagram using a Single IC TDA7294
Building a power hi-fi amplifier with MOS transistors requires the implementation of a relatively large number of components because, at the level of power stages, the connection between the bipolar transistors that make up the input stages and the MOS transistors of the output stages is far from simple. Fortunately, there is an elegant solution […]
Prevent Amplifier Fuse from Blowing During Power Switch ON
Is your power amplifier fuse blowing during power switch ON? It could be happening due to the initial high current drawn by the loudspeakers, when power is switched ON. The simple amplifier fuse protection circuits presented here can be effectively used for solving the issue. The problem is commonly seen in high power amplifiers, where […]
