The PAM2011Q is a filter-free, Class-D, 3W mono audio amplifier that delivers outstanding audio fidelity and up to 94% efficiency. Its ultra-low quiescent current (1.8mA) significantly extends battery life, making it ideal for automotive applications. The device requires minimal external components, streamlining system design and reducing overall costs for manufacturers.

Integrated overcurrent and overtemperature protection (OCP/OTP) with auto-recovery ensures reliable operation and safeguards the amplifier in demanding environments. The built-in de-pop circuit enables silent power-up and shutdown eliminating unwanted noise and enhancing the user experience. Available in the V-DFN2020-8/SWP (Type UXC) package with sidewall plating, the PAM2011Q supports SMT inspection and meets automotive-compliant reliability standards (more info).
