The evolution ofprecisionanalog-to-digitalconverters(ADCs)andhigh-fidelityaudio devices (codecs, MEMS microphones, etc.) continues to increase thedemand for high-performance audio and arbitrary signal generation in automatedtest equipment (ATE). The multiple high-performance instruments required tocharacterize,validate,andtestthedcandaccharacteristicsofthesedevicesimposeapremiumonthecostofdevelopmentandproductiontest,withsometimesprohibitive or limiting testcoverage.
When possible, test engineers develop in-house solutions as an alternative,butthiscomesattheexpenseoftimeandresources.Referencedesignssuchas the ADMX1002 ultra-low-distortion signal-generator module seek to offer analternativeto accelerate this development.
