Toshiba announced the launch of TCB702FNG, an addition to its 4-channel high-efficiency linear power amplifiers that meet current market requirements for high efficiency. With the new power amplifier, Toshiba has improved on its technology to realize efficiency comparable with a digital high efficiency of class D amplifier in actual operating range (0.5 to 4W). Power consumption is cut by up to 80% of that for a typical class AB amplifier.
The maximum output for TCB702FNG is 45W, and is pin-compatible with TCB701FNG, the company’s high efficiency linear power amplifier with maximum 50W output. Moreover, it also incorporates 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.
