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 4Ωload 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 HT4818/7 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip. It also utilizes circuitry to reduce “clicks and pops”during device turn-on.
