General Description

The AD1974 is a high performance, single-chip codec that provides four analog-to-digital converters (ADCs) with differential inputs using the Analog Devices, Inc.

patented multibit sigmadelta (Σ-Δ) architecture.

An SPI port is included, allowing a microcontroller to adjust volume and many other parameters.

Overview

4 ADC with PLL, 192 kHz, 24-Bit Codec AD1974.

Key Features

  • Phase-locked loop generated or direct master clock Low EMI design 107 dB dynamic range and SNR.
  • 94 dB THD + N Single 3.3 V supply Tolerance for 5 V logic inputs Supports 24 bits and 8 kHz to 192 kHz sample rates Differential ADC input Log volume control with autoramp function SPI®-controllable for flexibility Software-controllable clickless mute Software power-down Right justified, left justified, I2S, and TDM modes Master and slave modes up to 16-channel input/output Available in a 48-l.
