4ch Power Amplifier IC for car audio prevents speaker burnout
Toshiba Corporation launched a 4-channel power amplifier IC that can detect output offset voltage even during sound reproduction and prevents speaker burnout.
TCB501HQ IC detects output DC offset voltage caused by leakage from the input capacitor and other sources.
By integrating current-feedback system TCB501HQ prevents sound quality degradation at wide bandwidths.
