Power Amplifier 2x18W with TDA1516Q

Power Amplifier 2x18W with TDA1516Q
In many cars, cassette players use amplifiers that power does not exceed 5W with enough distortion to the limits of power. The problem is solved with the use of external amplifiers will have the opportunity to earn much more power with much less distortion. Given the voltage of the car is +12 V, we have the opportunity to take power over a threshold. The solution is to use two amplifiers in bridge connection, so the output quadrupled, at least

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
