Maxic Technology MT6802
The MT6802 is a 2.5W Class-D audio power amplifier. It is low noise, filter-free with PWM architecture, minimizing external component count, PCB area, system cost. The design of MT6802 is targeted for cellular phone aFEATURES
● Efficiency with an 8-Ω speaker: – 90% at 400 mW – 82% at 100 mW● Only three external components
● Optimized PWM output stage eliminates LC output filter
● Internally generated 300-kHz switching frequency eliminates capacitor and resistor.
● Fully differential design reduces RF rectification and eliminates bypass capacitor improved CMRR eliminates two input coupling capacitors
● Wafer Chip Scale Packaging (WCSP)
● Operating temperature: -40 ℃ - 85℃
● Over current and temperature protection APPLICATION CIRCUIT VDD Differential Input nSD VINN VDD PVDD Internal Oscillator VINP ________ Shutdown PWM Modulation VOP H-Bridge VON Bias GNDA GNDP Pop/Click Noise Suppression DESCRIPTIONS
