The LM4675SD/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 delivers a continuous average output of 2.2W into a 4,Ѷ speaker load with less than 1% total harmonic distortion plus noise (THD+N). The amplifier features a spread spectrum architecture that significantly reduces EMI, allowing for filterless operation with inductive loads, which minimizes external component requirements and simplifies design. This device includes externally configurable gain settings, a 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, contributing to low power consumption during idle periods. The LM4675 is packaged in a compact 8-pin WSON format, making it suitable for space-constrained applications such as mobile phones and portable electronic devices.
