STMICROELECTRONICS 100W DMOS Audio Amplifier IC, 10V to 40V, MultiWatt15
STMICROELECTRONICS 100W class AB audio amplifier IC with mute/stand-by. Features DMOS stage, low noise & distortion for Hi-Fi systems.
The STMICROELECTRONICS DMOS Audio Amplifier is a high-performance, monolithic integrated circuit designed for premium audio applications. Housed in a robust MultiWatt15 package, this 100W, class AB amplifier delivers exceptional sound quality with a very high operating voltage range of ±10V to ±40V, making it suitable for demanding Hi-Fi systems.
Its advanced DMOS (Diffusion Metal Oxide Semiconductor) power stage ensures efficient operation with minimal distortion and noise. Key user-friendly features include integrated muting and stand-by functions, which eliminate disruptive switch-on and switch-off noises, providing a seamless listening experience. The design also foregoes the need for traditional Boucherot cells (Zobel networks), simplifying circuit design.
Core Features & Protection
Engineered for reliability, this amplifier IC incorporates comprehensive protection mechanisms. It includes short-circuit protection to safeguard the device and connected components from damage, alongside thermal shutdown to prevent overheating during prolonged use or in high-temperature environments.
