I’ll walk you through the amplifier design process as I build a 25 Watt stereo amplifier withthe TDA2050. First, I’ll show you how to calculate the voltage and current requirements of your power supply, and show you how find a properly sized heat sink. Then, I’ll show you how to...
A multiplexer is used to control various gains of this PGIA circuit by selecting the LT5400 quad resistor network. When selecting a multiplexer for this wide bandwidth discrete PGIA design, the multiplexer’s important parameters such as on resistance (RON), on capacitance (CON), and of...
an NPN transistor connected in such a way behaves as an amplifier but it doesn't always amplify there are certain conditions for that right so in this example we'll explore this in great detail we'll understand under what conditions our transistor acts as an amplifier and under what condition...

How to Select the Best Audio Amplifier for Your DesignRobert Nicoletti
An RF bias tee uses low-pass and high-pass filtering to separate AC and DC power, such as in power amplifiers.
In the last section, we saw that an amplifier's job is to take a weak audio signal and boost it to generate a signal that is powerful enough to drive a speaker. This is an accurate description when you consider the amplifier as a whole, but the process inside the amplifier is a littl...
Simply adding an AC-coupling capacitor to the input of the transimpedance amplifier in a pulsed application can harm the performance of your system. However, trade-offs can be made to achieve realistic goals depending on your needs. Not all systems require the best recovery times ...
