Key Specifications The HWD2163 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. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones. Audio power amplifie.

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: An HWD2163IUP or HWD2163IVG that has been properly mounted to a circuit board will deliver 2.2W into 4Ω. The other package options for the HWD2163 will deliver 1.1W into 8Ω.
