WM8948 Product details

DESCRIPTION
The WM8948 is a highly integrated low power hi-fi CODEC designed for portable devices such as digital still cameras.
Up to 6 analogue inputs may be connected; a 2-channel digital microphone interface is also provided. Flexible output mixing options support single-ended and differential configurations, with outputs derived from the digital audio paths or from analogue bypass paths. Twin stereo outputs or stereo line and mono BTL headphone/speaker drive may be supported.

FEATURES
• Hi-fi audio CODEC
    - 94dB SNR during ADC recording (‘A’ weighted)
    - 96dB SNR during DAC playback (‘A’ weighted)
• 6 analogue audio inputs
• Integrated bias reference for electret microphones
• 2-channel digital microphone interface
• Powerful digital mixing / DSP functions:
    - 3D-stereo enhancement
    - 5-notch filters
    - 5-band equalizer (EQ)
    - ReTune™ parametric filter
    - Dynamic range control and noise gate
    - Low-pass/High-pass filters
    - Direct Form 1 (DF1) programmable digital filter
• Digital beep generator
• 4 analogue audio outputs
• Stereo line output
• Mono BTL headphone/speaker output driver
• I2S digital audio interface - sample rates 8kHz to 48kHz
• Frequency Locked Loop (FLL) frequency conversion / filter
• Video buffer function
• 4-wire Touch Panel interface controller
• Auxiliary ADC for DC measurement or battery monitoring
• Integrated LDO low-noise voltage regulator
• 36-ball W-CSP package (2.96 x 3.06 x 0.7mm, 0.5mm pitch)

APPLICATIONS
• Digital Still Cameras (DSC)
• Multimedia phones
