WM8753CLGEFL/V

Overview

The WM8753CLGEFL/V is a low-power stereo CODEC with an integrated Voice CODEC, designed for portable digital telephony and Hi-Fi playback. It features a Hi-Fi DAC interfacing over I2S with sample rates from 8 to 96kHz, achieving 98dB SNR and -84dB THD at 48kHz. The ADC provides 95dB SNR and -82dB THD. On-chip drivers include a cap-less headphone amplifier delivering 40mW into 16Ω at 3.3V and a speaker driver outputting 0.5W into 8Ω. The device supports dual differential microphone inputs with programmable ALC and noise cancellation. Operating voltages range from 1.8V to 3.6V, with power consumption under 20mW in all-on mode at 2V supplies.

Feature Summary

• Integrates high-quality Hi-Fi DAC and ADC alongside a dedicated Voice CODEC interface for simultaneous or selectable operation.
• Includes on-chip cap-less headphone and speaker drivers, eliminating the need for external coupling capacitors.
• Features dual differential microphone interfaces supporting noise cancellation and programmable automatic level control.
• Incorporates internal phase-locked loops to generate system clocks from various master clock frequencies.

Applications

• Mobile phones
• Bluetooth stereo headsets
• MP3 players and recorders

Procurement Notes

Verify the ordering code WM8753CLGEFL/V matches the required temperature range of -25°C to +85°C and the 48-lead QFN package. Confirm moisture sensitivity level MSL3 requirements are met for storage and handling. Ensure the specific suffix indicates the correct reel quantity if tape and reel packaging is needed, as standard reels contain 2,200 units.

Selection Notes

Select this component when a single chip must handle both high-fidelity audio playback and telephony voice processing. The integrated cap-less outputs simplify PCB layout by reducing external component count. Verify that the available master clock frequencies align with the system's PLL requirements for the desired audio sample rates.

Part Context

This part belongs to the Wolfson Microelectronics WM8753L family, which combines Hi-Fi and telephony capabilities. The CLGEFL/V suffix denotes the commercial temperature range and the specific 48-lead QFN package variant. Related parts in the series may offer different packaging options or slight variations in power management features while maintaining the core codec functionality.

Replacement Considerations

Direct substitutes within the same family include the WM8753CLGEFL/RV, which shares identical electrical characteristics but is supplied in tape and reel packaging instead of tube. Other variants like the WM8753LGEB/V may exist but require verification of package and temperature specifications before substitution.
