LN4890 - 1W Differential Audio Power Amplifiers

Description

The LN4890 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

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

Features

  • Available in space-saving packages Ultra low current shutdown mode BTL output can drive capacitive loads Improved pop & click circuitry eliminates noises during turn-on and turn-off transitions 2.2 - 5.0V operation No output coupling capacitors, snubber networks or bootstrap capacitors required Thermal shutdown protection Unity-gain stable External gain configuration capability.

LN4890 Low-Cost, Mono/Stereo, 1 W Differential Audio Power Amplifiers ■ General Description The LN4890 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V DC power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LN4890 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.
