LTC1967CMS8#TRPBF

Overview

The LTC1967CMS8#TRPBF is a precision RMS-to-DC converter manufactured by Analog Devices Inc. It operates on a single 5V supply and draws a typical supply current of 340µA. The device utilizes an 8-pin MSOP package for surface-mount installation. This component is designed for high-accuracy signal processing applications requiring direct conversion of AC signals to DC levels.

Feature Summary

• Provides true RMS to DC conversion using proprietary delta-sigma calculation technology
• Features rail-to-rail output with independent reference pin for flexible level shifting
• Supports both single-ended and differential inputs for enhanced EMI/RFI suppression
• Operates with low power consumption suitable for portable instrumentation

Applications

• Precision LVDT signal conditioning systems
• True RMS digital multimeters and panel meters
• AC+DC measurement instruments
• Portable battery-powered instrumentation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct package type and shipping format. Check official distributor channels for current availability status as supply may be limited.

Selection Notes

Select this component for applications requiring high linearity and low power consumption in RMS detection. Ensure the input signal characteristics align with the device's dynamic range capabilities. Consider the MSOP package constraints for PCB layout and thermal management requirements in dense designs.

Part Context

This part belongs to the LTC1967 series of precision RMS-to-DC converters from Analog Devices. It shares functional similarities with the LTC1966 but offers specific performance optimizations for industrial and measurement applications. The CMS8 designation identifies the commercial temperature range and MSOP package variant within the product family.

Replacement Considerations

The LTC1966CMS8#TRPBF is a documented related device within the same product family offering similar RMS-to-DC functionality. Verify pin compatibility and specific parameter differences before substitution.
