Toshiba Launches Current-Feedback 4ch Power Amplifier IC for Car Audio with Built-In Full-Time Offset Detection

TOKYO — (BUSINESS WIRE) — April 27, 2016Toshiba Corporation's (TOKYO:6502) Storage & Electronic Devices Solutions Company today announced the launch of “TCB501HQ,” 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 June 2016.

The new IC integrates a newly developed, full-time offset detection circuit. Conventional offset detection during sound reproduction is difficult. Toshiba’s new IC detects output DC offset voltage caused by leakage from the input capacitor and other sources, even during sound reproduction, and prevents speaker burnout.

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.
