WM9713CLGEFL/RV

Overview

The WM9713CLGEFL/RV is a highly integrated AC'97 audio and touchpanel codec designed for mobile computing. It features stereo DACs with 94dB SNR and ADCs with 87dB SNR, alongside on-chip headphone (45mW) and speaker (400mW) drivers. The device supports resistive touchpanels with 12-bit resolution and includes an auxiliary mono DAC. It operates on 1.8V to 3.6V supplies within a -25°C to +85°C temperature range, housed in a 48-lead QFN package.

Feature Summary

• Dual CODEC architecture supporting hi-fi stereo via AC-Link and voice functions via PCM interface
• Integrated capacless headphone and speaker output drivers
• Resistive touchpanel interface with pen-down detection in sleep mode
• On-chip PLL for flexible clock generation from various input frequencies

Applications

• Smartphones
• Personal Digital Assistants (PDA)
• Handheld and Tablet Computers

Procurement Notes

Verify the specific ordering suffix RV indicates tape and reel packaging with a quantity of 2,200 units. Confirm the Pb-free status and MSL3 moisture sensitivity level align with assembly requirements. Ensure the -25 to +85°C operating temperature range meets the target application's environmental specifications before finalizing procurement.

Selection Notes

Select this component when a single IC must handle both high-fidelity audio playback/recording and resistive touch digitization. The internal PLL allows operation with non-standard master clocks. Verify that the required sample rates and power consumption levels fit within the device's capabilities, particularly noting the separate supply domains for digital and analog sections.

Part Context

This part belongs to the Cirrus Logic WM9713L family, which serves as a pin-compatible upgrade to the WM9712. The series integrates multiple analog front-end functions into a compact form factor suitable for space-constrained portable electronics. The CLGEFL designation specifies the leadless QFN package type used in this variant.

Replacement Considerations

The WM9713CLGEFL/V is a compatible alternative offering identical electrical characteristics but supplied in trays rather than tape and reel.
