LM4910MA General Description

The LM4910MA is a versatile mono bridge-tied load (BTL) audio power amplifier suitable for a wide range of portable electronic devices. With its supply voltage range of 2.7V to 5.5V and maximum output power of 1.3W, this amplifier is capable of delivering high-quality audio in compact devices such as cell phones, MP3 players, and digital cameras. Its low quiescent current consumption of only 4mA makes it an ideal choice for battery-powered applications, ensuring efficient power usage and extended battery life. The inclusion of a shutdown mode further enhances its energy-saving capabilities, reducing the supply current to less than 1µA when the amplifier is not in use. In addition, the LM4910MA prioritizes safety with its thermal shutdown protection feature, automatically powering down the amplifier in high-temperature conditions to prevent damage and ensure reliable operation. The built-in short-circuit and thermal-overload protection, along with its small 8-pin SOIC package size, make the LM4910MA a reliable and compact solution for audio power amplification in portable electronic devices
