LN4818 - Dual 2.2W Audio Amplifier Plus Stereo Headphone Function

Description

The LN4818 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω load with less than 1.0% THD+N.

In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.

Features

  • an externally controlled, low-power consumption shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and pops” during device turn-on.

Dual 2.2W Audio Amplifier Plus Stereo Headphone Function LN4818 ■ General Description The LN4818 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω load with less than 1.0% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones. Boomer audio power amplifiers were designed specifically to provide high quality output power from a surface mount package while requiring few external components. To simplify audio system design, the LN4818 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
