Introduction

AI Translation

The SSM2211 is a 3W mono Class AB audio power amplifier. It operates from a supply voltage range of 1.9–5.5V in a BTL bridge configuration. At a 5V supply, it delivers an average output power of 3.0W into a 4Ω load with THD less than 10%. In shutdown mode, the typical current consumption is less than 0.5μA. The device is designed to provide ample power and high-fidelity audio output with minimal external components, requiring no output coupling capacitors or bootstrap capacitors. Available in SOP-8 and DFN-8 packages to help save board space, it is well suited for mobile phones and a wide range of portable devices employing low-voltage, low-power solutions.
