The WM8786 is a stereo audio ADC with differential inputs designed for high performance recordable media applications. Data is provided as a PCM output. Stereo 24-bit multi-bit Delta Sigma ADCs are used with digital audio output word lengths of 16 to 32 bits, and sampling rates from 8 kHz to 192 kHz. The device also has a high pass filter to remove residual DC offsets. 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.
