Overview
The AD1877JRZ-RL, produced by Analog Devices Inc., is a stereo, 16-bit oversampling Analog-to-Digital Converter (ADC) based on Sigma Delta (∑∆) technology. This device is primarily designed for digital audio bandwidth applications and operates on 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. The AD1877JRZ-RL features an on-chip voltage reference that is stable over temperature and time, defining the full-scale range for both channels. The digital output data from both channels are time-multiplexed to a single, flexible serial interface, supporting both master and slave modes.
