Wolfson Microelectronics has added to its Pure Sound audio portfolio with the introduction of the WM8783, an ultra low pin count, low power stereo ADC solution 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 claims to feature the lowest ADC pin count on the market today and requires only two decoupling capacitors. The low power WM8783 is also ideal for battery powered applications, providing system designers with an easy-to-use, high quality line-in conversion path, resulting in savings on design time, PCB space and the audio subsystem bill of materials (BOM).
The WM8783 uses a high performance multi-bit Sigma Delta ADC architecture to provide an audio performance that achieves 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 3.3 V supply. The WM8783 accepts analogue inputs up to 1 Vrms and provides an integrated high pass filter to remove DC offset and suppress low frequency noise.
The WM8783 is available for sampling now in a SOIC-8 package.
WM8783 customer evaluation boards are available to aid device evaluation and development.
