HWD2163
Description
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 amplifiers were designed specifically to provide high quality output power from a surface mount package while requiring few external ponents. To simplify audio system design, the HWD2163 bines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
The HWD2163 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...
