WM9081GICN/V

Overview

The WM9081GICN/V is a mono digital-to-analog converter (DAC) with an integrated Class AB/D speaker driver, dynamic range controller, and ReTune Mobile parametric equalizer. It delivers up to 2.6W peak power into a 4Ω load. In Class D mode, it achieves a signal-to-noise ratio of 92dB (A-weighted), while Class AB mode provides 97dB SNR. The device supports sample rates from 8kHz to 96kHz and features a low-power frequency-locked loop (FLL). It operates within a -40°C to +85°C temperature range and is housed in a 28-lead COL package.

Feature Summary

Integrated mono DAC with 2.6W Class AB/D speaker driver
ReTune Mobile Parametric Equalizer with fully programmable coefficients
Programmable dynamic range controller for loudness optimization and clipping protection
Supports standard 2-wire, 3-wire, 4-wire, and hardware control interfaces

Applications

Portable navigation systems
Mobile phones
Flat panel TVs

Procurement Notes

Verify the ordering suffix 'V' indicates tape and reel packaging with a quantity of 3500 units. Confirm the package type is the 28-lead COL (4x4x0.55mm) with MSL3 moisture sensitivity level. Ensure the component meets the Pb-free specification and operates within the -40°C to +85°C temperature range.

Selection Notes

Select this component for space-constrained portable applications requiring high power output at low distortion. Choose Class D mode for higher efficiency or Class AB mode for superior audio fidelity. Ensure the system design accommodates the required supply voltages: DCVDD/DBVDD between 1.71V and 3.6V, AVDD between 2.7V and 3.6V, and SPKVDD between 2.7V and 5.5V.

Part Context

The WM9081GICN/V is part of the Cirrus Logic WM9081 series, designed specifically for mobile multimedia applications. It integrates digital audio processing capabilities directly with the power stage, eliminating the need for external Class D filters and reducing PCB track lengths. This integration helps minimize emissions and crosstalk in multi-channel systems.
