The Texas Instruments LM4671ITL is a high-efficiency, 2.5W, mono, Class-D audio amplifier. It features an analog input and a filterless PWM architecture, which reduces external component count and simplifies design. The amplifier operates on a single supply voltage ranging from 2.4V to 5.5V and can drive a 4Ω speaker load.
Key electrical specifications include an output power of 2.5W and a low THD + N of 0.09% at 1 kHz. The device offers high efficiency, with typical values reaching 88% at 3.6V and 400mW into an 8Ω speaker. It also features a very fast turn-on time of 17μs (typ) and a micro-power shutdown mode.
The LM4671ITL is available in a space-saving DSBGA (YZR) package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C. This amplifier is designed to meet the demands of portable devices, offering a compact and efficient audio amplification solution.
