DESCRIPTION
The WM8953 is a low power high performance stereo ADC designed for mobile handsets and other portable devices.
Four single-ended or differential input connections are provided, with up to 60dB of analogue gain in each input path. Stereo 24-bit sigma-delta ADCs provide hi-fi quality audio recording of microphones or line input. A programmable high pass filter is available in the ADC path for removing DC offsets and suppressing wind and other low frequency noise. A low noise microphone bias with programmable current detect and short-circuit detect is provided. A flexible digital audio interface supports most commonly-used clocking schemes. The audio interface supports TDM and tristate outputs allow multiple devices to share the same interface. An integrated low power PLL provides support for most commonly-used audio sample rates. The WM8953 is supplied in very small and thin 42-ball WCSP package, ideal for portable systems. |
