The RMS to DC Click Board™ is used to convert the RMS of the input signal into a DC voltage, with a value directly readable over the I2C interface. The Click Board™ is equipped with the LTC1968, an RMS-to-DC converter IC, which outputs an analog voltage depending on the RMS value of the input signal. The key feature of this IC is its very good linearity of the output voltage with respect to the RMS of the input signal. This is due to the innovative delta-sigma computational technique, used in this IC. Besides high linearity, this IC also features a high accuracy, high signal bandwidth, and good thermal stability. It can be used to accurately measure the RMS value of various alternating signals.
