BiCD joins BiCMOS in audio PA

Toshiba America Electronic Components Inc has introduced a Class-KB audio power amplifier based on bipolar, complementary metal oxide semiconductor and double-diffused metal oxide semiconductor (BiCD) technology.

Designated TB2905HQ, the new audio power amplifier joins a growing family of BiCD power amplifiers engineered for demanding car-audio applications, including CD, DVD and navigation applications.

TB2905HQ incorporates four bridge-tied load (BTL) amplifier channels and its many built-in functions include standby switching, muting, offset and clipping detection, and various protective circuits.

"Toshiba Corporation, a leader in automotive electronics solutions, developed its proprietary Class-KB high-efficiency amplifier architecture for car electronics to overcome the serious shortcomings of competing high-efficiency solutions.

Class-KB completely eliminates the switching noise or electromagnetic interference associated with digital or switched analog amplifier designs.

TB2905HQ, the first Class-KB amplifier based on BiCD technology, is a linear analog amplifier that provides high efficiency with excellent fidelity and is another advance in Toshiba's growing product offering for the car-audio market," said David Cruikshank, business development manager in the ASSP Business Unit at TAEC.

"With uncompromised audio fidelity and high efficiency, TB2905HQ supports the current automotive trend of rapidly proliferating entertainment and infotainment systems contained in ever smaller electronics enclosures."

Samples and production quantities of TB2905HQ are available now. Current pricing is $5.00 each in 10,000-piece quantities.
