Combining PWM with a small R-2R ladder improves both. It reduces PWM ripple significantly and increases the DAC’s resolution. In this Design Idea, an eight-resistor array and three output pins ...

The first step in selecting and using high-precision D/A converters is to consider the DAC architecture that is best for a given application. Several architectures are available, including oversampled ...

The R-2R ladder, a well known resistor topology, is often used to implement a current or voltage 6-dB step attenuator. By appropriately scaling the resistor values ...

Sometimes it seems as though digital designers get all of the attention. In all of the excitement surrounding "gigaFLOPS," "22 nm," and such, there's still one crumb of comfort for we non-digital ...
