Audio DAC Boasts Of Lowest Distortion

Claiming to have the world's lowest distortion figure,the WM8740 audio d/a converter offers an SNR of 117 dB and THD of –105 dB (0.000562%) for a stereo ‘A' weighted signal. The device offers three modes of operation. Normal mode uses on-board digital filters to minimize components.

In 8f_s mode, internal digital filters are bypassed to use the device with an external DSP-based filter or HDCD decoder. Available in a 28-lead SSOP package for 3- to 5-V operation, pricing is set at $2.94 each/10,000.
