Low Pin Count Stereo ADC operates from single 3.3 V supply.

Press Release Summary:

Requiring only 2 decoupling capacitors, low power WM8783 uses multi-bit Sigma Delta ADC architecture to offer high quality line input audio in recordable media applications, including LCD TVs, set top boxes, and DVD recorders. It achieves 95 dB SNR, -83 dB THD, and supports sample rates from 8-96 kHz. Offered in SOIC-8 package, ADC accepts analog inputs up to 1 Vrms and provides integrated high pass filter to remove DC offset and suppress low frequency noise.

Wolfson Launches Industry's Lowest Pin Count Consumer Stereo ADC

Edinburgh, UK - Wolfson Microelectronics plc (LSE: WLF.L), today announces a new addition to its Pure Sound audio portfolio with the introduction of the WM8783, an ultra low pin count, low power stereo ADC designed to offer high quality line input audio performance in recordable media applications, including LCD TVs, set top boxes and DVD recorders.

The WM8783 is an easily integrated, simple 'plug and play' device requiring a single 3.3 V supply. The WM8783 has the lowest ADC pin count on the market today and requires only two decoupling capacitors. The low power WM8783 is also well suited for battery powered applications, providing system designers with an easy-to-use, high quality line-in conversion path, resulting in significant savings on design time, PCB space and the audio subsystem bill of materials.

The WM8783 uses a high performance multi-bit Sigma Delta ADC architecture to provide superior audio performance achieving 95 dB SNR, -83 dB THD and supporting sample rates from 8 kHz to 96 kHz. The WM8783 also simplifies system design through the use of on-chip regulators to enable operation from a single 3.3V supply. The WM8783 accepts analogue inputs up to 1Vrms and provides an integrated high pass filter to remove DC offset and suppress low frequency noise.

Barry Paterson, Wolfson's Director of Engineering for High Performance Audio, said, "The WM8783 offer customers a simple cost effective solution without any compromise on performance. The WM8783 is easy to use and requires minimal external components to realize an effective solution."

Price and Availability

The WM8783 is available for sampling now in a SOIC-8 package. For 1k quantities, the WM8783 is priced at $0.48. WM8783 customer evaluation boards are available to aid device evaluation and development.
