GENERAL DESCRIPTION
The ADAU1962 is a high performance, single chip, digital-
to-analog converter (DAC) that provides 12 DACs with
differential outputs using the Analog Devices, Inc., patented
multibit sigma-delta (Σ-Δ) architecture. A SPI/I2C port is included,
allowing a microcontroller to adjust volume and many other
parameters. The ADAU1962 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 ADAU1962 is designed for low electromagnetic interference
(EMI), evident in both the system and circuit design architectures.
By using the on-board phase-locked loop (PLL) to derive the
internal master clock from an external left right frame clock
(LRCLK)/frame clock, the ADAU1962 eliminates 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 of a smaller amplitude,
further reducing emissions.
The ADAU1962 is available in an 80-lead LQFP package. Note
that throughout this data sheet, multifunction pins, such as
SCLK/SCL/SA, are referred to by the entire pin name or by a
single function of the pin, for example, SCLK, when only that
function is relevant.
