AD1870 is a single-supply 5V 16-bit stereo ADC with single-ended dual-channel analog inputs, 92dB (typical) dynamic range, 0.006dB decimator pass-band ripple, fourth order 64x oversampling, 256 or 384x input clock, flexible serial output interface, etc.
The AD1870 is a stereo, 16-bit oversampling analog-to-digital converter (ADC) based on sigma-delta technology, intended primarily for digital audio bandwidth applications requiring a single 5 V power supply. It features a fourth-order one-bit noise shaping modulator and a digital decimation filter for each channel, with an on-chip voltage reference defining the full-scale range.
