Power consumption up to 90% lower than general class AB amplifier

December 7, 2017

TOKYO - Toshiba Electronic Devices & Storage Corporation today announced a new 4-channel high-efficiency linear power amplifier "TCB701FNG," that meets current market requirement for high efficiency. Sample shipments will start in January, 2018.
 

With "TCB701FNG," the company has improved on its technology to realize efficiency comparable with a digital high efficiency, class D amplifier in actual operating range (0.5 to 4W). Power consumption is cut by up to 90% of that for a typical class AB amplifier.
 

The new amplifier also includes a self-diagnosis function with I2C bus control that can diagnose errors and contribute to a suitable set design by changing the detection setting for gain or time constants. It also includes full-time error detection of output DC offset voltage, which can quickly detect abnormal output offset voltage and prevent speaker burnout, improving set reliability.
