The LM4667ITL/NOPB is a fully integrated, filterless, high-efficiency switching audio amplifier designed for mobile and portable communication devices. It operates on a single supply voltage ranging from 2.7V to 5.5V and is capable of delivering up to 1.3W of output power. The amplifier features selectable gain options of 6dB or 12dB and has a very fast turn-on time of approximately 5ms. This device utilizes a delta-sigma modulation technique that minimizes output noise and total harmonic distortion (THD), achieving less than 1% THD+N at a continuous average output of 450mW into an 8Oc load. The LM4667 also includes built-in short circuit protection and a micro-power shutdown mode, which reduces power consumption to 0.01OºA in shutdown. The amplifier is available in space-saving DSBGA and VSSOP packages, making it suitable for applications where board area is a concern. Its efficiency ratings are competitive, with typical efficiencies of 74% at 100mW and 84% at 450mW output levels when powered at 3V. The LM4667 is ideal for engineers looking for a compact, efficient audio amplification solution for portable devices.
