Product Description
The CJC1808 device is a high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. The CJC1808 device uses a delta-sigma modulator with 64-times oversampling and includes a digital decimation filter and high-pass filter that removes the dc component of the input signal. For various applications, the CJC1808 device supports master and slave mode and two data formats in serial audio interface.
Fabrication of the CJC1808 device uses a highly advanced CMOS process. The device is available in a small, 14-pin TSSOP package.
