Product Introduction

Overview

The FDA2100LV is a high-performance, fully digital single-chip class D amplifier designed by STMicroelectronics. It is specifically intended for automotive audio applications, particularly in car radio systems. This amplifier utilizes BCD6-SOI (Silicon On Insulation) technology, integrating a high-performance D/A converter with powerful MOSFET output amplifiers. This integration enables outstanding efficiency compared to traditional class AB amplifiers. The device features a built-in step-up driver, allowing up to 150 W output power with a standard 14 V supply voltage, and is compliant with recent OEM specifications for low voltage operation during engine stop-start conditions, contributing to reduced emissions and environmental protection.
