ADAU1978 Datasheet Quad Analog-to-digital Converter

Manufacturer: Analog Devices

Overview: Data Sheet Quad Analog-to-Digital Converter (ADC) ADAU1978.

General Description

The ADAU1978 incorporates four high performance, analogto-digital converters (ADCs) with 2 V rms capable ac-coupled inputs.

The ADCs use a multibit sigma-delta (Σ-Δ) architecture with continuous time front end for low EMI.

An I2C/serial peripheral interface (SPI) control port is included that allows a microcontroller to adjust volume and many other parameters.

Key Features

  • Four 2 V rms differential inputs On-chip phase-locked loop (PLL) for master clock Low electromagnetic interference (EMI) design 109 dB analog-to-digital converter (ADC) dynamic range Total harmonic distortion + noise (THD + N):.
  • 95 dB Selectable digital high-pass filter 24-bit stereo ADC with 8 kHz to 192 kHz sample rates Digital volume control with autoramp function I2C/SPI controllable for flexibility Software-controllable clickless mute Software power-down Right justified, left justif.
