BL6312 - 2.7W/CH Stereo Filter-Free Class-D Audio Power Amplifier

Description

The BL6312 is a 2.7-W high efficiency, stereo, filter-free class-D audio power amplifier in QFN20 package that requires only two external components.

Features

  • Output power: 2.7W/Ch with 4Ω loader at VDD=5V 1.5W/Ch with 8Ω loader at VDD=5V Low supply current (Typical 7mA quiescent current) Low shutdown current (Typical 0.4µA shutdown current) Thermal protection and output over current protection are designed Optimized PWM output stage eliminates LC output filter Independent shutdown control for each channel Select gain of 6, 12, 18, 24 dB Internally generated 300-kHz switching frequency eliminates capacitor and resistor Internal pull-down resistor on s.
