The TDA7385 amplifier circuit is a 4-channel car amplifier application that operates with a single supply. Thanks to its 12-18 V DC supply, 4 Ω speaker outputs, standby and mute..

One of the most important problems in electrode heater systems is that the current drawn also increases as the liquid temperature rises. The system, which starts operating with low current..

The phase-controlled photovoltaic excess energy router circuit gradually transfers the energy at the inverter’s 230V AC output to a resistive load when the battery voltage rises above the set level…

The UNI-T UT61E multimeter has the ability to connect to a computer through an RS-232-based interface, transfer measurement data to the screen, and record it. However, with this method, a..

The light switch-off delay circuit is a 230V AC compatible MOSFET timer that keeps the LED lamp on for a short time after the wall switch is turned off. It..

Recoil creates a short-term but very sudden acceleration effect in firearm or simulation-purpose mechanical systems. To measure this effect, in practice it is often more suitable to use a high-speed..

Our reader @Uğur EKER shared his complete car amplifier project built around the TDA7294 and UPC494. The PCB design has been carefully prepared. The sound quality is very good and..

TDA7294 IC: 100W DMOS Amplifier Features. The TDA7294 is a popular Class AB audio power IC with a DMOS output stage, offered by STMicroelectronics in a Multiwatt-15 package and used..

High-Performance Class AB Amplifier Design. For electronics enthusiasts and professionals who want to build high-power sound systems, the MATRIX 1.4-DOS-V amplifier circuit is a highly successful and field-proven power amplifier..

A Class D amplifier circuit designed for bass guitar. In addition, bass-guitar-specific tone-shaping Equalizer options and a preamplifier are available. More than 150W of power was obtained. When the amplifier..
