Toshiba Power amplifier
July 19, 2016

Toshiba Electronics Europe has introduced a 49W-per-channel power amplifier IC, designed for automotive audio applications. The four-channel TCB501HQ provides high output power and low distortion and detects output offset voltage. Similar to high-end hi-fi audio systems the IC integrates a current feedback system. This prevents sound quality degradation at wide bandwidths, improving sound consistency and the listening experience. Conventional offset detection during sound reproduction is particularly difficult to manage. To…
