Analog Devices Inc. AD1877JRZ

Description
The AD1877 is a stereo, 16-bit oversampling ADC based on Sigma Delta (ΣΔ) technology intended primarily for digital audio bandwidth applications requiring a single 5 V power supply. Each single-ended channel consists of a fourth-order one-bit noise shaping modulator and a digital decimation filter. An on-chip voltage reference, stable over temperature and time, defines the full-scale range for both channels. Digital output data from both channels are time-multiplexed to a single, flexible serial interface. The AD1877 accepts a 256 x F, or a 384 x F input clock (F, is the sampling frequency) and operates in both serial port "master" and "slave" modes. In slave mode, all clocks must be externally derived from a common source.
