WM9082 - PDM Input Mono 3W Class D Speaker Driver

Description

The WM9082 is a high-performance sigma-delta Class D speaker driver.

Audio input is supported using a stereo PDM interface; clock and control-code detection circuitry supports all of the audio and control functions via a 2-wire interface.

Features

  • include a low-power mute state, and output slew-rate control. Short-circuit and thermal protection is provided. The WM9082 is supplied in a 9-ball 1.56 x 1.46mm CSP package, with 0.5mm ball pitch.

w WM9082 PDM Input Mono 3W Class D Speaker Driver DESCRIPTION The WM9082 is a high-performance sigma-delta Class D speaker driver. Audio input is supported using a stereo PDM interface; clock and control-code detection circuitry supports all of the audio and control functions via a 2-wire interface. The digital audio interface provides excellent noise immunity, eliminating traditional input-filtering components. The flexible 2-wire interface minimises the PCB footprint and simplifies software development. The combined audio and control interface configuration is ideal for enabling the WM9082 to be located close to the speaker; this reduces the length of the output connections, giving good EMC performance and removing the need for output filter components.
