LTC1966MPMS8#PBF

Overview

The LTC1966MPMS8#PBF is a precision, micropower true RMS-to-DC converter manufactured by Analog Devices Inc. It utilizes an innovative patented delta-sigma computational technique to achieve high accuracy and low power consumption. The device operates on a single supply voltage ranging from 2.7V to 5.5V or dual supplies up to ±5.5V. It features a constant bandwidth that remains unaffected by input voltage levels. The component is housed in an 8-pin MSOP package designed for space-constrained applications.

Feature Summary

• Employs delta-sigma computational technology for true RMS-to-DC conversion
• Offers rail-to-rail output with independent output reference pin for flexible level shifting
• Supports both single-ended and differential inputs for enhanced EMI/RFI suppression
• Features ultra-low shutdown current capability for extended battery life

Applications

• True RMS digital multimeters
• Panel meters
• AC+DC measurement systems
• Handheld measurement devices

Procurement Notes

Verify the specific suffix 'MP' against official Analog Devices documentation to confirm military-grade qualification status. Ensure the order matches the exact part number including the '#PBF' lead-free designation. Confirm package type is MSOP-8. Validate RoHS compliance through manufacturer datasheets prior to procurement.

Selection Notes

Select this component when precise RMS-to-DC conversion is required in portable or battery-operated environments. The device is suitable for applications demanding low power consumption and high linearity. Consider the MSOP package size for compact designs. Verify input signal characteristics match the device's common-mode and differential voltage ranges.

Part Context

This part belongs to the LTC1966 family of RMS-to-DC converters. The family is characterized by its use of delta-sigma computation rather than traditional logarithmic methods. This approach simplifies usage and improves accuracy across a wide dynamic range. The series is designed for modern precision measurement applications requiring minimal external components.
