The LM4854MT is a monaural audio amplifier from Quarktwin Technology Ltd. designed for both bridge-tied load (BTL) and single-ended (SE) stereo headphone applications. It operates on a single 5V supply, providing a typical output power of 1.1W into an 8,Ѷ load and 1.7W into a 4,Ѷ load in BTL mode, while delivering 85mW to 32,Ѷ loads in SE mode. The amplifier features a circuit topology that suppresses output transients, eliminating the need for output coupling capacitors, which reduces component count and board space. It includes three inputs for stereo and mono signals, making it versatile for various applications. The LM4854MT is suitable for portable devices such as PDAs, cellular phones, and notebook computers, and it requires minimal external components. Additional features include a micropower shutdown mode, low power standby mode, and thermal shutdown protection. The device is available in a compact 14-lead TSSOP package.
