Productoverzicht

The WM8950CGEFL/V is an Analog-to-digital Converter (ADC) with microphone input and programmable digital filters. It is a low power, high quality mono ADC designed for portable applications. The device integrates support for a differential or single ended mic. External component requirements are reduced as no separate microphone amplifiers are required. Advanced Sigma Delta converter is used along with digital decimation filters to give high quality audio at sample rates from 8 to 48ks/s. Additional digital filtering options are available, to cater for application filtering such as wind noise reduction, noise rejection, plus an advanced mixed signal ALC function with noise gate is provided. An on-chip PLL is provided to generate the required master clock from an external reference clock. The PLL clock can also be output if required elsewhere in the system. It operates at supply voltages from 2.5 to 3.6V, although the digital supplies can operate at voltages down to 1.71V to save power.
  • Programmable high pass filter
  • Fully programmable IIR filter
  • On-chip PLL
  • Low-noise bias supplied for electret microphones
  • Multiple auxiliary analogue inputs
