Product Summary

The LT1088CD is a thermally based RMS-DC converter building block. It converts the input waveform to heat. The LT1088CD’high voltage breakdown allows crest factor measurements of 50:1 and operation over a 20:1 input dynamic range. The applications of the LT1088CD are wideband RMS voltmeters, RF leveling loops, wideband AGC, high crest factor measurements, SCR power monitoring.
