Mikroelektronika MIKROE-3311 RMS-to-DC Click Precise RMS-to-DC Converter

Technical description of the product (MIKROE-3311):

MIKROE-3311 LTC1968 precise RMS-to-DC converter with wide input signal bandwidth. The RMS to DC click is a Click board™ that 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 high accuracy, high signal bandwidth, and good thermal stability. It can be used to accurately measure the RMS value of various alternating signals. Applications: RMS to DC click is an ideal solution for development of various true RMS digital multimeter applications, panel meters and gauges, AC + DC measurement applications, a true RMS measurement of an audio signal and other similar applications that require accurate RMS value readings. On-board modules: LTC1968 (Linear Technology, Analog Devices) and MCP3221 (Microchip). Key features: excellent linearity that allows direct application with no compensation elements required, a rail-to-rail common mode voltage, a true RMS-to-DC conversion with a minimum number of external components, a good thermal stability, a very wide signal bandwidth, and more. Interface: GPIO, I2C. Input Voltage: 3.3V or 5V. Click board size: M (42.9 x 25.4 mm).
