Toshiba Corporation today announced that it has launched a 4 channel power amplifier IC, "TB2941HQ", that improves noise tolerance in audio systems in cars with engine idling reduction systems. Samples are available now with mass production scheduled to start in July 2013.Engines of cars with idling reduction systems often cut out, causing battery voltage to drop. By reducing the minimum operation voltage from 8V to 6V, the new power amplifier realizes stable operation and makes it possible to prevent the loss of sound and noise in car audio. This IC improves noise tolerance with a newly developed filter circuit, and minimizes the influence of cellular phone waves on the sound. Reinforced protection circuits realize high reliability.
