DESCRIPTION

· The LTC1967 is a true RMS-to-DC converter utilizing delta-sigma computational technology for enhanced linearity, accuracy, and temperature stability.

· It supports both single-ended and differential input signals with a rail-to-rail common mode range and a 1V PEAK differential input.

· Designed for easy system calibration, it operates on a single power supply from 4.5V to 5.5V and features a low power shutdown mode.

· Packaged in an 8-pin MSOP, it is ideal for portable applications.

FEATURES

· High linearity of 0.02% facilitates straightforward system calibration.

· Wide input bandwidth up to 40kHz with minimal gain error, independent of input voltage amplitude.

· Simplified true RMS-DC conversion requiring only one external capacitor.

· Low supply current of 330mA typical and ultralow shutdown current of 0.1mA.

· Flexible input and output configurations including rail-to-rail outputs and a separate output reference pin for level shifting.

APPLICATIONS

· Ideal for true RMS digital multimeters and panel meters.

· Suitable for true RMS AC + DC measurements in various electronic systems.
