Programmable Analog for High Power LED Color Mixing Applications

Programmable analog circuitry adds analog functionality to reprogrammable digital electronics. The combination provides flexibility to end users and offers unique advantages to designers in particular applications. For instance, High Power LED color mixing applications have relatively loose timing requirements, but there are nine parameters that need to be measured in a typical RGBW (red, green, blue, white) application: four LED forward voltage signals, four LED current waveforms, and the board temperature. Each signal type requires a different signal conditioning topology. The optimal solution to measure each signal accurately is programmable analog.  For more information on this topic, click the download link above or read the full article on Programmable Logic DesignLine."
