WM9712CLGEFL/RV

Overview

The WM9712CLGEFL/RV is an AC'97 audio and touchpanel codec manufactured by Wolfson Microelectronics. It integrates stereo DACs with a 94 dB SNR and stereo ADCs with a 92 dB SNR, supporting variable rate audio up to 48 kHz. The device includes a 45 mW headphone driver and a 400 mW mono speaker driver. It features a resistive touchpanel interface with 12-bit resolution, auxiliary ADC inputs, GPIO pins, and battery monitoring comparators. Operating voltages range from 1.8 V to 3.6 V. The component is housed in a 48-lead QFN package (7x7 mm) and supports an operating temperature range of -25°C to +85°C.

Feature Summary

AC'97 Rev 2.2 compatible stereo CODEC with tone control and bass boost
Integrated touchpanel digitizer supporting 4-wire and 5-wire panels
On-chip headphone and speaker drivers for direct connection
Auxiliary mono DAC for ring tones and DC level generation

Applications

Personal Digital Assistants (PDA)
Smartphones
Handheld and Tablet Computers

Procurement Notes

Verify the specific suffix RV indicates tape and reel packaging with a reel quantity of 2,200 units. Confirm the moisture sensitivity level is MSL3 and peak soldering temperature is 260°C. Ensure the ordering information matches the leadless QFN package type and Pb-free status.

Selection Notes

Select this component for mobile systems requiring integrated audio and touch functionality via a single AC-Link interface. Consider the power consumption characteristics across different supply voltages and operating modes. Verify compatibility with the host controller's digital interface timing and voltage levels.

Part Context

The WM9712L is a highly integrated input/output device designed for mobile computing. It combines audio recording, playback, touchpanel digitization, and battery monitoring into a single chip. The device reduces system component count by directly connecting to microphones, headphones, speakers, and touchpanels.
