TDA7850 ST Audio Amplifier | 25FLEXIWATT（垂直） | 4x50W, MOSFET Output

Product Overview

The TDA7850 is a breakthrough MOSFET audio amplifier from STMicroelectronics, designed for high-power car audio systems. It integrates four independent amplifier channels capable of delivering 50W each into 4Ω loads, with a maximum output power of 4x50W at 14.4V supply voltage and 10% THD. The device features a high-efficiency MOSFET output stage, low distortion, and a wide supply voltage range (8V to 18V). It is housed in the 25FLEXIWATT (vertical) package, which offers excellent thermal performance and compact footprint for space-constrained applications.
