DIOPAM8302AASCR

Overview

The PAM8302AASCR is a 2.5W mono Class-D audio power amplifier designed for high-efficiency audio playback in portable applications. It features a filterless architecture that allows the device to drive speakers directly without the need for external low-pass LC filters, reducing both board space and system cost. Operating from a 2.0V to 5.5V supply, it is ideal for battery-powered devices and low-voltage logic systems.

Why Choose This Part

The component offers high efficiency and extremely low quiescent current of 4mA to 8mA, extending battery life in idle states. Its filterless design and MSOP-8 package minimize the PCB footprint while built-in thermal and short-circuit protection improve system reliability.

Applications

Getting Started

To use the PAM8302AASCR, provide a stable 2V to 5.5V supply to VDD and keep the input signal trace lengths short to minimize noise. Use a 1uF ceramic capacitor close to the VDD pin for decoupling and pull the shutdown pin high to enable the device. Since this is a bridge-tied load (BTL) amplifier, do not connect either side of the speaker output to ground.
