Product Summary

The AD1877JRZ is a stereo, 16-bit oversampling ADC. The AD1877JRZ is based on Sigma Delta technology intended primarily for digitalaudio bandwidth applications requiring a single 5 V power supply. Each single-ended channel consists of a fourth-order one-bitnoise shaping modulator and a digital decimation filter. An on-chip voltage reference, stable over temperature and time, definesthe full-scale range for both channels. Digital output data from both channels are time-multiplexed to a single, flexible serialinterface. Applications include Consumer Digital Audio Receivers, Digital Audio Recorders, Including Portables CD-R, DCC, MD and DAT, Multimedia and Consumer Electronic Equipment, Sampling Music Synthesizers and Digital Karaoke Systems.
