Monoblock Car Amplifier TDA7294

Monoblock Car Amplifier TDA7294
Monoblock Car Amplifier circuit TDA7294 is based on an article "Improving the power amplifier IC TDA7294" Journal of the radio, № 11 2005. This mono car amplifier has a sufficiently high reliability, high capacity, high-quality bass. Monoblock Car Amplifier circuit is shown above. The difference from the original circuit only in the output transistor using a better replacement. (more…)

Car Amplifier Circuit 2x40W based TDA8560Q

Car Amplifier Circuit 2x40W based TDA8560Q
IC TDA8560, being a complete analogue of the well-known chip TDA1557Q, in fact - its a whole new amp. This car amplifier circuit gives an output power 40 watts per channel at 2 ohm load, and 22 Watts on 4 ohms load. Perhaps you are wondering how to get 40 watts of power? And answer is : you can find 2 ohm speakers (if any), or you can connect an amplifier with a pair of 4 ohm speakers in

2x22W Car Audio Amplifier Circuit

2x22W Car Audio Amplifier Circuit
Above is a schematic diagram of an amplifier which is used in car audio. This circuit uses IC TDA 1558 from Philips. TDA1558 is a monolithic integrated class-B Output power amplifier in 17-lead single-in-line (SIL) plastic package. The device contains 4 x 11 W single-ended or 2 x 22 W BTL amplifiers. (more…)

Car Power Amplifier based TDA1562

Car Power Amplifier based TDA1562
Audio amplifier is built with the main component of Philips TDA1562 IC. The TDA1562 is a monolithic integrated 70 W/4 W. Bridge-Tied Load (BTL) class-H high efficiency power amplifier in a 17 lead DIL-bent-SIL plastic power package. Its essence is that to a certain value output (approx. 20 watts) amplifier operates in the mode B. If the output power increases further, included a clever scheme to increase the voltage output stage and thus enables the amplifier to swing to
