The circuit in Figure 1 can help if you must transfer dc power and audio over a pair of copper wires. One application for such a circuit is a low-cost door-opening system with speech input. The ...

The circuit was designed to produce a power amplifier with the utilization of TDA7294 integrated circuit to drive audio circuits for 60 Watts power. Power Amplifier – a type of amplifier built and ...

A power supply with a novel resonant topology enables an audio system with the efficiency, no-load and size advantages of SMPS, but very low-generated EMI. Dr. Mahesh de Silva, Senior Applications ...

Rohm has introduced ‘high-fidelity’ power supply ICs aimed at audio devices requiring high-resolution audio play-back. Above the quality of CD audio, it sees high-resolution audio sources typically ...

ISSCC, the International Solid-state circuits conference, is the IEEE’s annual showcase for all that is best in on-chip circuit design from across the globe. Thousands of engineers will flock there ...

We are sometimes asked our opinion of exotic power cords, and have met more than a few people who have laid out some serious investment to have what they see as the very best sort of cord running from ...

”Switching power supply” is a generic term that describes a power source with a circuit to convert dc to ac voltages that can be further processed into another dc voltage. Switching power supply can ...
