Toshiba Introduces Superior Surge Resistance Power Amplifier for Automotive Audio
Toshiba Electronic Components and Storage Co., Ltd. (Toshiba) has introduced a new car audio 4-channel power amplifier TCB503HQ with excellent anti-surge performance. Sample shipments will start on the same day, and volume production is scheduled to begin in the first quarter of 2019.
The new product adopts Toshiba's mature car audio IC development capability, and achieves higher reliability by using the anti-surge analog fine process. The IC also supports 6V operating voltage and is suitable for vehicles with popular idle-stop systems in recent years. This function effectively suppresses popping caused by power supply voltage fluctuations.
Other features include built-in filters to increase immunity to external high-frequency noise, such as high-frequency noise from cell phone radio waves and rearview mirror adjustments to prevent abnormal noise.
By using the chip's clip detection signal to control the volume and tone control circuitry, the sound quality can be improved.
