Linear Technology LTC1967IMS8#PBF

Description
The LTC1967 is a precision RMS-to-DC converter that utilizes an innovative delta-sigma computational technique. It offers exceptional linearity and accuracy, with a bandwidth independent of input voltage amplitude. The device operates with single-ended or differential input signals, supporting crest factors up to 4. The LTC1967 simplifies system calibration and provides a rail-to-rail output with a separate output reference pin for flexible level shifting. It operates on a single power supply from 4.5V to 5.5V and features an ultralow shutdown current of 0.1μA. The LTC1967 is packaged in a space-saving MSOP package, making it ideal for portable applications.
