The LM4675TL/NOPB from Texas Instruments is a single-supply, high-efficiency Class-D audio amplifier designed for mono applications. It delivers up to 2.7W of output power into a 4Ω load.
This amplifier utilizes a spread spectrum, filterless PWM architecture that significantly reduces EMI, eliminating the need for output filters when driving inductive loads. Key electrical specifications include a wide analog supply voltage range of 2.4V to 5.5V and a low THD + N of 0.03% at 1kHz.
Designed for minimal external components, the LM4675TL/NOPB offers externally configurable gain, a very fast turn-on time of 17μs, and "click and pop" suppression circuitry. It also features a micro-power shutdown mode for power conservation.
The device is available in space-saving WSON and DSBGA packages, making it suitable for compact designs. Its operating temperature range is -40°C to 85°C.
