Wolfson Microelectronics WM8786
The WM8786 is a stereo audio ADC with differential inputs designed for high performance recordable media applications. The device also has a high pass filter to remove residual DC offsets. The device is hardware controlled.DESCRIPTION
Data is provided as a PCM output. Stereo 24-bit multi-bit sigma-delta ADCs are used with digital audio output word lengths of 16 to 32 bits, and sampling rates from 8kHz to 192kHz. The device is hardware controlled. Pin programming provides access to all features including oversampling rate, audio format, powerdown, master/slave control and digital signal manipulation. The device is supplied in a 20-lead SSOP package. WM8786FEATURES
