AC Measurement IC operates to 500 kHz with 1% accuracy.

AC Measurement IC operates to 500 kHz with 1% accuracy.

True RMS-DC converter ICs LTC1967 and LTC1968 measure energy of AC signal regardless of waveform shape. With 0.02% linearity, there is no need for in-system calibration, and delta-sigma computational technique is inherently immune from changes vs. temperature, time, and PCB stress. Rail-to-rail inputs can be driven single-ended or differentially, and rail-to-rail outputs feature separate output...
