WM8941 Product details

DESCRIPTION
The WM8941 is a low power, high quality mono CODEC designed for portable applications such as digital still cameras or camcorders.
The device integrates support for a differential or single ended mic, and includes drivers for speakers or headphone, and mono line output. External component requirements are reduced as no separate microphone or headphone amplifiers are required. A high performance, low power current-mode video buffer provides inherent short circuit protection.

FEATURES
• Mono CODEC:
• Audio sample rates:8, 11.025, 16, 22.05, 24, 32, 44.1, 48kHz
• DAC SNR 98dB, THD -84dB (‘A’-weighted @ 8 – 48ks/s)
• ADC SNR 94dB, THD -80dB (‘A’-weighted @ 8 – 48ks/s)
• On-chip Headphone/Speaker Driver
    - 40mW output power into 16Ω
    - BTL speaker drive 0.4W into 8Ω
• Additional MONO Line output
• Multiple analog or ‘Aux’ inputs, plus analog bypass path
• Mic Preamps :
• Differential or single end Microphone Interface
    - Programmable preamp gain
    - Pseudo differential inputs with common mode rejection
    - Programmable ALC / Noise Gate in ADC path
• Low-noise bias supplied for electret microphones

OTHER FEATURES
• Integrated video buffer with LPF and clamp.
• Digital Playback Limiter
• Programmable high pass filter (wind noise reduction)
• 4 notch filters (narrowband noise suppression)
• On-chip PLL
• Low power, low voltage
    - 2.5V to 3.6V (digital: 1.71V to 3.6V)
• 4x4x0.75mm 28 lead QFN package

APPLICATIONS
• Digital still cameras and camcorders
• General purpose mono audio CODEC with video buffer
