Consumer stereo ADC touts low pin count

Edinburgh, UK—Wolfson Microelectronics plc has added to its Pure Sound audio portfolio a low pin count, low power stereo ADC that offers high quality line input audio performance in recordable media applications, including LCD TVs, set top boxes and DVD recorders.

Designated WM8783, the ADC is an easily integrated, simple plug-and-play device requiring a single 3.3 V supply. According to Wolfson, 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.

The WM8783 uses a high performance multi-bit Sigma Delta ADC architecture to provide 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 analog inputs up to 1Vrms and provides an integrated high pass filter to remove DC offset and suppress low frequency noise.

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