100 Watt Power Amplifier Circuit 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 […]
75 Watt Power Amplifier Circuit
Our power amplifier only uses a handful of widely available and inexpensive components. Despite this, it can deliver an effective power output of 50 W into an 8 ohm load […]
LM12 IC Datasheet, Application Circuits
LM12 is a power operational amplifier integrated circuit (IC) developed by National Semiconductor (now owned by Texas Instruments). It is designed for use in high-power audio amplifiers, servo amplifiers, and […]
BC636 Transistor Datasheet [45 V 1 Amp PNP Transistor]
The BC636 is a PNP bipolar junction transistor (BJT) that is specifically designed for low noise amplifier and switching applications. Here’s the complete datasheet of the transistor BC636. Pinout Configuration […]
IC 7805 Switching Regulator Circuit
Starting from a classical linear regulation, we will present the evolution towards a simple switching version. This will allow us to analyze the operation without going through the classical theoretical […]
