The LM4675TLX/NOPB is a mono Class D audio power amplifier designed for high efficiency and low electromagnetic interference (EMI). It operates on a single supply voltage ranging from 2.4V to 5.5V and can deliver up to 2.65W of output power into a 4,Ѷ load with less than 1% total harmonic distortion plus noise (THD+N). The amplifier features a spread spectrum architecture that minimizes EMI and eliminates the need for an output filter, thereby reducing the overall component count and simplifying design. This device includes externally configurable gain settings, a very fast turn-on time of approximately 17Oºs, and integrated "click and pop" suppression circuitry to enhance audio quality. It also supports a micro-power shutdown mode, making it suitable for battery-operated devices. The LM4675TLX/NOPB is available in a compact 9-bump DSBGA package, which is advantageous for space-constrained applications such as mobile phones and portable electronic devices.
