LM4862 Amplifier Circuit – A Better LM386 Alternative
The LM386 based amplifier is still very popular as one of the smallest sized amplifier chips. However, the LM386 is not perfect and has a few drawbacks and limitations. As shown below, the LM386 works with large electrolytic capacitors, which makes it bulkier and costlier, and causes it to be prone to distortions with age. […]

How Varactor (Varicap) Diodes Work
A varactor diode, also called varicap, VVC (voltage-variable capacitance, or tuning diode, is a type of semiconductor diode which features a variable voltage-dependent capacitance on its p-n junction when the device is reversed biased. Reverse bias basically means when the diode is subjected to an opposite voltage, meaning a positive voltage at the cathode, and […]
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 […]
Schottky Diodes – Working, Characteristics, Application
Schottky barrier diodes are semiconductor diodes designed with minimal forward voltage and fast switching speeds which may be as low as 10 ns. These are manufactured in current ranges of 500 mA to 5 amps and up to 40 V. Due to these features they become specifically suitable in low voltage, high frequency applications such […]
