The AD193X family are high performance, single-chip codecs that
provide 4 ADCs with differential input and 8 DACs with either
single-ended or differential output using ADI’s patented multibit
sigma-delta architecture. An SPI® or I2C® port is included, allowing
a microcontroller to adjust volume and many other parameters.
The AD193X family operates from 3.3V digital and analog supplies.
The AD193X is available in a 48-lead (SE output) or 64-lead
(differential output) LQFP package.
The AD193X 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 master clock from L-R clock, the
AD193X eliminates the need for a separate high frequency master
clock. It can also be used with a suppressed bit clock. The D-A and
A-D converters are designed using the latest ADI continuous time
architectures to further minimize EMI. By using 3.3V supplies,
power consumption is minimized, further reducing emissions.
