| Description | The IS31AP2005-SLS2-TR is a high-efficiency, mono Class-D audio power amplifier from Lumissil Microsystems, designed for portable and battery-powered applications. It delivers up to 2.95 W into a 4 Ω load at 5 V supply with 10% total harmonic distortion plus noise (THD+N), and 1.70 W into an 8 Ω load under the same conditions . Operating over a supply voltage range of 2.7 V to 5.5 V, the amplifier maintains high efficiency, reaching up to 89% at 400 mW with an 8 Ω speaker . Its filter-less PWM architecture eliminates the need for output filters, reducing external component count and simplifying design. The device features differential inputs, integrated pop-and-click suppression circuitry, and short-circuit and thermal protection. Housed in a compact 8-MSOP package, it is suitable for applications such as mobile devices, portable audio equipment, and educational toys. |
