The HT91808 device is a high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. The HT91808 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 HT91808 device supports master and slave mode and two data formats in serial audio interface.
The device is available in TSSOP14 package.
