AD1879JD

Analog To Digital Converters (ADC) Overview

The AD1879JD is a single-supply, 16-bit stereo analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features dual-channel single-ended analog inputs and operates on a single 5 V power supply. The device delivers a typical dynamic range of 92 dB and an S/(THD+N) ratio of 90 dB. It utilizes a fourth-order, 64-oversampling modulator combined with a three-stage, linear-phase decimator. The input clock can be configured for 256 fs or 384 fs sampling rates. Key specifications include less than 100 µW typical power consumption in normal operation, a power-down mode, and an on-chip voltage reference. It employs a flexible serial output interface and is housed in a 28-lead SOIC package.
