BL6281 - 1.1 Watt Audio Power Amplifier

General Description

The BL6281 is a Class-AB audio power amplifier designed for mobile phone, MID and other portable communication devices.

It is capable of delivering 1.1 watts of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.

Key Features

  • Improved PSRR at 217 Hz & 1 KHz 60 dB Power output at 5.0V, 1% THD+N, 8Ω 1.1 W (typ. ) Ultra low shutdown current 0.1 uA (typ. ) 2.2V.
  • 5.5V operation Improved circuitry eliminates pop-click noise during turn-on and turn-off transitions No output coupling capacitors, snubber networks or bootstrap capacitors required Unity-gain stable External gain configuration capability Packages: MSOP8、SOP8 General.
