LM4890MMX/NOPB General Description

The LM4890 audio power amplifier is a cutting-edge solution for demanding applications in mobile phones and other portable communication devices. Its key features include the ability to deliver up to 1 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V DC power supply. This amplifier is designed specifically to provide high-quality output power with minimal external components, making it ideal for low-voltage applications where power consumption is a primary concern

Key Features

Silicon-Gate Technology
Enhanced Audio Filtering
Compact Design and Low Power Consumption
Frequency Stability and Low Noise Performance
Advanced Thermal Management
Improved Linearity and Signal-to-Noise Ratio
