The CXAR41199 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W into a 4Ω load or 2.5W into a 3Ω load with typically 1% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.
To simplify audio system design, the CXAR41199 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
The CXAR41199 features a low power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “pop/click” during device turn-on
