DDS IC plus frequency-to-voltage converter make low-cost DAC

Posted on Jan 27, 2013

Precision DACs are essential in many consumer, industrial, and military applications, but high-resolution DACs can be costly. Frequency-to-voltage converters have good nonlinearity specificationstypically, 0.002% for the AD650and are inherently monotonic. This Design Idea shows how you can use a frequency-to-voltage converter and a DDS (direct-digital-synthesizer) chip for precise digital-to-analog conversion.
