What are the key features of LTC1966MPMS8#PBF?
- Delta-sigma RMS computation delivers 0.15% max linearity error for precision true-RMS AC measurement across wide crest factors
- Micropower operation with very low quiescent current enabling battery-powered handheld measurement instruments
- Differential input accepts signals up to ±5.5 V peak for direct connection to current shunts and attenuated voltage signals
- MP-grade version provides extended -55°C to 125°C temperature range for demanding industrial and military applications
What is LTC1966MPMS8#PBF used for?
LTC1966MPMS8#PBF is used in precision true-RMS AC voltmeters, power meters, and energy monitoring systems where accurate measurement of non-sinusoidal waveforms with high crest factors is required. It serves as the RMS conversion element in industrial clamp meters, motor current monitors, and harmonic analysis instruments operating from dual ±5 V supply rails. The MP-grade temperature rating and micropower design also make it suitable for remote sensor nodes and avionics instruments requiring stable RMS measurement across the full -55°C to 125°C range.

Frequently Asked Questions
What is the linearity error specification of LTC1966MPMS8#PBF, and why does it matter for AC power measurement?
LTC1966MPMS8#PBF has a maximum linearity error of 0.15% across its input range, ensuring that the DC output accurately represents the true RMS value of the input signal. This precision is essential in power analyzers and energy meters where errors exceeding 0.5% fail IEC 62053 class 1 metering accuracy requirements.
How does the delta-sigma RMS computation in LTC1966MPMS8#PBF handle high crest-factor waveforms compared to traditional log-antilog converters?
LTC1966MPMS8#PBF's delta-sigma architecture computes RMS without the log-domain approximations that introduce crest-factor errors in traditional converters. It accurately measures signals with crest factors up to 4 at full scale and beyond with reduced input amplitude, maintaining less than 0.15% error on distorted industrial waveforms.
What temperature range does the MP grade of LTC1966MPMS8#PBF cover, and in which demanding environments is this required?
The MP grade of LTC1966MPMS8#PBF is specified for a -55°C to 125°C operating temperature range, making it suitable for military avionics, automotive under-hood monitoring, and oil-field instrumentation environments where standard commercial-grade ICs operating only to 85°C cannot guarantee reliable performance.
Can LTC1966MPMS8#PBF operate from a single 5 V supply, or does it require a dual supply?
LTC1966MPMS8#PBF is specified for a dual ±5 V supply with negative supply voltage up to -5.5 V. Single-supply operation is not directly supported in this grade, but the device can measure AC signals riding on a mid-rail DC bias in single-supply systems by AC-coupling the input and setting the reference pin at VCC/2.
