AD1928 Datasheet 2 Adc/8 Dac

Manufacturer: Analog Devices

Overview: 2 ADC/8 DAC with PLL, 192 kHz, 24-Bit Codec AD1928.

General Description

The AD1928 is a high performance, single-chip codec that provides two analog-to-digital converters (ADCs) with differential input and eight digital-to-analog converters (DACs) with single-ended output using the Analog Devices, Inc., patented multibit sigma-delta (Σ-Δ) architecture.

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

The AD1928 operates from 3.3 V digital and analog supplies.

Key Features

  • PLL-generated or direct master clock Low EMI design 108 dB DAC/107 dB ADC dynamic range and SNR.
  • 94 dB THD + N 3.3 V single supply Tolerance for 5 V logic inputs Supports 24 bits and 8 kHz to 192 kHz sample rates Differential ADC input Single-ended DAC output Log volume control with autoramp function SPI® controllable for flexibility Software-controllable clickless mute Software power-down Right-justified, left-justified, I2S-justified, and TDM modes Master and slave modes up to 16-chann.
