CSMSC HWD2163
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. The HWD2163 features an externally controlled, low-power consumption shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. To simplify audio system design, the HWD2163 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.

GENERAL DESCRIPTION
Key Specifications 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 components. 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. See the Application Information sections for further information concerning the HWD2163IUP and HWD2163IVG. n PO at 1% THD+N n HWD2163IVG, 3Ω,4Ω loads 2.5W(typ), 2.2W(typ) n HWD2163IUP, 3Ω,4Ω loads 2.5W(typ), 2.2W(typ) n HWD2163IUP, 8Ω load 1.1W(typ) n HWD2163, 8Ω 1.1W(typ) n Single-ended mode THD+N at 75mW into 32Ω 0.5%(max) n Shutdown current 0.7µA(typ) n Supply voltage range 2.0V to 5.5V FEATURES
