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 16?
- BTL speaker drive 0.4W into 8?
? 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)
