MIX2018 Overview

MIX2018 4.8W single-channel Class F audio power amplifier

Features

Class F amplifier single channel amplifier

• MIX2018 is a high efficiency, filter-free 4.8W mono Class F audio amplifier. Its ultra-low EMI makes it ideal for portable devices with FM functions.

• The single-ended input architecture and extremely high PSRR of MIX2018 effectively improve the ability of MIX2018 to suppress RF noise. The filter-free PWM modulation structure and built-in gain reduce external components, PCB area and system cost, and simplify the design. Up to 90% efficiency, fast startup time and small package size make MIX2018 the best choice for portable audio products.

• MIX2018 has a shutdown function, which greatly extends the system's standby time. The overheat protection function enhances the system's reliability. The POP sound suppression function improves the system's auditory experience and simplifies system debugging.

• MIX2018 is available in ESOP8 lead-free package with heat sink.

Parameters

• Patented F-Class Architecture

• D mode output power: 4.8W (VDD=5.0V, RL =2Ω, THD+N=10%)

• F mode output power: 4.8W (VDD=5.0V, RL =2Ω, THD+N=10%)

• Operating voltage: 2.5V to 5.1V

• Low distortion and low noise

• Power-on POP sound suppression function

• Shutdown current is less than 1uA

• Overheat protection function

Application

Bluetooth speakers, card speakers, amplifiers
