HWD4863 - Dual 2.2W Audio Amplifier

General Description

TheHWD4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω load (Note 1) or 2.5W to a 3Ω load (Note 2) with less than 1.0% THD+N.

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. Note 1: AnHWD4863MTE or HWD4863LQ that has been properly mounted to a circuit board will deliver 2.2W into 4Ω. The other package options for the HWD4863 will deliver 1.1W into 8Ω. See the.

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, theHWD4863 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
