GENERAL DESCRIPTION
The ADAU1966 is a high performance, single-chip DAC that
provides 16 digital-to-analog converters (DACs) with differen-
tial output using the Analog Devices, Inc., patented multibit
sigma-delta (Σ-Δ) architecture. An SPI/I2C port is included,
allowing a microcontroller to adjust volume and many other
parameters. The ADAU1966 operates from 2.5 V digital, 5 V
analog and 3.3 V or 5 V input/output supplies. A linear regulator
is included to generate the digital supply voltage from the analog
supply voltage. The ADAU1966 is available in an 80-lead LQFP
package.
The ADAU1966 is designed for low EMI. This consideration is
apparent in both the system and circuit design architectures.
By using the on-board PLL to derive the internal master clock
from an external LRCLK, the ADAU1966 can eliminate the
need for a separate high frequency master clock and can be
used with or without a bit clock. The DACs are designed using
the latest Analog Devices continuous time architectures to
further minimize EMI. By using 2.5 V digital supplies, power
consumption is minimized, and the digital waveforms are a
smaller amplitude, further reducing emissions.
