BL6290 - 1.25 Watt Audio Power Amplifier

Description

The BL6290 is a Class-AB audio power amplifier designed for mobile phones and other portable communication devices.

It is capable of delivering 1.25 watts of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.

Features

  • Improved PSRR at 217 Hz & 1 KHz 64 dB Power output at 5.0V, 1% THD+N, 8Ω 1.25 W (typ. ) Power output at 3.0V, 1% THD+N, 8Ω 450 mW (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 Available in space-saving packages: MSOP8,SOP8 General D.
