HT4818 - Dual 2.2W AUDIO AMPLIFIER

Download the HT4818 datasheet PDF. This datasheet also covers the HT4817 variant, as both devices belong to the same dual 2.2w audio amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The HT4818/7 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.

Key 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.

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 HT4818/7 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
