WM9010ECSN/R

Overview

The WM9010ECSN/R is a low power stereo headphone driver utilizing Class G technology for high efficiency. It features ground-referenced, cap-less outputs and an integrated charge pump generating split-rail supplies from a single VDD source. The device accepts 1Vrms line level inputs and delivers up to 28mW into a 32Ω load. Key electrical parameters include a 104dB SNR (A-weighted), 750μA quiescent current at enable, and operation within a -40°C to +85°C temperature range.

Feature Summary

Class G amplifier architecture ensures high power efficiency and minimal quiescent current consumption.
Integrated charge pump circuit generates split-rail voltage supplies for ground-referenced headphone drivers.
Silent Switch technology provides pop and click suppression during device enable or disable transitions.
Cap-less output design eliminates the need for external DC-blocking capacitors on the audio path.

Applications

Mobile handsets
Portable media players (PMP)
Notebooks and laptop computers
LCD televisions

Procurement Notes

Verify the specific ordering suffix 'ECSN/R' against the manufacturer's latest documentation to confirm package type, moisture sensitivity level, and tape-and-reel quantity specifications. Ensure compatibility with system voltage requirements and thermal management needs before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high-efficiency stereo audio amplification in space-constrained portable devices. The integrated charge pump simplifies the bill of materials by removing external boost circuits. Verify that the 12-pin CSP package dimensions fit the target PCB layout constraints.

Part Context

Originally manufactured by Wolfson Microelectronics plc, this component is part of the low-power audio subsystem family. Cirrus Logic acquired Wolfson Microelectronics, and the product line continues under the Cirrus Logic brand. The WM9010 serves as a dedicated solution for driving headphones in mobile and consumer electronics.
