The AD7723 also has a 200- W standby mode. The table provides a few additional points of comparison.
Evaluation boards are available for each type.
Increased bandwidth is typically pursued with single-loop modulators by increasing the order of integration in the loop. To improve bandwidth by increasing the ODR rate of such converters would be difficult because it would require a more costly manufacturing process and power-hungry integrating amplifiers capable of settling to the required accuracy. To reduce the effect of quantization noise further, in both the AD9260 and AD7723, the quantization noise added by the DACs is first measured and then subtracted digitally. AD9260 block diagram. The decimation filter's stopband rejects frequencies between 1.25 and 18.75 MHz, substantially easing antialiasing requirements on the analog input.
