Toshiba Corporation’s Storage & Electronic Devices Solutions Company today announced the launch of the TCB502HQ, a 4-channel power amplifier IC that detects output offset voltage that is a factor in speaker burnout. Mass production is scheduled to start in December 2016.
To respond to growing demand for superior sound quality of car audio, the new IC integrates a current-feedback system of the type adopted in high-end hi-fi audio. This prevents sound quality degradation at wide bandwidths and offers consistent sound quality, considering overtone of musical instruments or human voice.
The new IC also integrates a newly developed, full-time offset detection circuit. It detects offsets generated at the output stage even during playback and contributes to reduction of field failures, thus helping ensure high reliability.
