Dual 2.1W Audio Power Amplifier Plus Stereo Headphone Function 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

   产品概述 返回TOPqr7嘉泰姆

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.qr7嘉泰姆

To simplify audio system design, the CXAR41199 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.qr7嘉泰姆

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.qr7嘉泰姆

The CXAR41199 is available in Green TSSOP-20 (Exposed Pad), TQFN-3×3-20L, TSSOP-16 (Exposed Pad), SOIC-16 and DIP-16 packages. It operates over an ambient temperature range of -40℃</span> to +85℃</span>.qr7嘉泰姆
