Overview: TB2905HQ
TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic TB2905HQ
Class KB High-Efficiency, Low-Frequency Power Amplifier IC Maximum Power: 47 W × 4 Channels
The TB2905HQ is a high-efficiency class KB power amplifier IC developed for car audio applications that incorporates four BTL amplifier channels. It employs a pure complementary DMOS output stage www.DataSheet4U.com consisting of P-ch upper and N-ch lower sections, offering a maximum output power (POUT) of 47 W. Class KB (keyed BTL) amplifiers exhibit less than half the heat generation of comparable class AB solutions under normal operating conditions. Therefore, it is possible to design a smaller Weight: 7.7 g (typ.) heatsink and maintain lower internal temperature in the car audio sets. Additionally, the TB2905HQ has many built-in functions for car audio, such as standby switching, muting, protective circuits, and self diagnosis.
