WM8976GEFL/RV概述

CODEC, STERO, SPEAKER DRIVER, 32QFN

DESCRIPTION

The WM8976 is a low power, high quality CODEC designed for portable applications such as multimedia phone, digital still camera or digital camcorder.

The device integrates a preamp for differential microphone, and includes drivers for speakers, headphone and differential or stereo line output. External component requirements are reduced as no separate microphone or headphone amplifiers are required.

FEATURES

Stereo CODEC:

• DAC SNR 98dB, THD -84dB ‘A’ weighted @ 48kHz

• ADC SNR 95dB, THD -84dB ‘A’ weighted @ 48kHz

• On-chip Headphone Driver with ‘capless’ option

   - 40mW per channel into 16Ω / 3.3V SPKVDD

• 0.9W output power into 8Ω BTL speaker / 5V SPKVDD

   - Capable of driving piezo speakers

   - Stereo speaker drive configuration

Mic Preamps:

• Differential or single-ended microphone interfaces

   - Programmable preamp gain

   - Psuedo differential input with common mode rejection

   - Programmable ALC / Noise Gate in ADC path

• Low-noise bias supplied for electret microphone

Other Features:

• Enhanced 3-D function for improved stereo separation

• Digital playback limiter

• 5-band Equaliser record or playback

• Programmable ADC High Pass Filter wind noise reduction

• Programmable ADC Notch Filter

• Aux inputs for stereo analog input signals or ‘beep’

• On-chip PLL supporting 12, 13, 19.2MHz and other clocks

• Support for 8, 11.025, 12, 16, 22.05, 24, 32, 44.1 and 48kHz sample rates
