Product Details

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 3.3 V digital and analog supplies. The AD193X is available in a 48-lead or 64-lead 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 3.3 V supplies, power consumption is minimized, further reducing emissions.
