Product Description

Introduction:

The TDA7498 is the first amplifier in the market rated at 100W + 100W and features an advanced sixth generation BCD6S process (bipolar / CMOS / DMOS) that supports monolithic integrated analog, logic and high voltage capability. Compared with other Class D amplifiers, ST's BCD6S process achieves higher chip area energy efficiency, crosstalk reduction and improved sound quality. In addition, the BCD6S allows NMOS and PMOS complementary transistors to be integrated into high-power output circuits eliminating the need for external bootstrap capacitors and cathode-mounted diodes required by legacy processes. This method system simplifies design, saves board space, and improves product design reliability.
