What are the key features of LTC1968IMS8?
- True RMS-to-DC conversion with 0.15% maximum linearity error enables accurate power measurement of complex and non-sinusoidal waveforms
- Low 2700 µA quiescent current in a compact 8-pin MSOP package suits battery-powered and space-constrained measurement instruments
- Wide bandwidth delta-sigma conversion technique replaces traditional log-antilog RMS circuits, improving measurement accuracy from DC to 20 kHz
What is LTC1968IMS8 used for?
The LTC1968IMS8 is designed for precision RMS voltage and power measurement in industrial energy monitors, digital multimeters, and automated test equipment. Its 0.15% linearity error and true RMS response make it accurate for non-sinusoidal and distorted AC waveforms common in switching power supply outputs and variable-speed motor drives. The 8-pin MSOP footprint allows integration into portable instruments and PCB-mounted sensing modules with minimal board space.

Frequently Asked Questions
What is the maximum linearity error and bandwidth of the LTC1968IMS8, and how do these specs compare to a log-antilog RMS converter?
The LTC1968IMS8 achieves a maximum linearity error of 0.15% with an effective bandwidth up to 20 kHz, significantly outperforming log-antilog RMS converters which typically exhibit 1% or greater linearity error above a few kilohertz. Its delta-sigma computation handles crest factors up to 4 on a 1 V RMS input, making it accurate for distorted AC signals common in switching power supply and motor drive measurements.
Which precision measurement instruments can embed the LTC1968IMS8 to add true RMS capability without a separate analog front-end IC?
Digital multimeters, clamp-on power meters, industrial energy loggers, and automated test system signal conditioning boards can integrate the LTC1968IMS8 directly. The 8-pin MSOP package with only 2700 µA supply current from a 3.3 V or 5 V rail and a single external averaging capacitor of 1 µF to 100 µF replaces discrete log-antilog circuits, reducing BOM cost and PCB area in handheld and rack-mount instruments.
When sourcing the LTC1968IMS8 for a production run, what lead times and alternative Analog Devices RMS converters should procurement teams consider?
The LTC1968IMS8 in the 8-pin MSOP package is an industrial-grade part rated from -40 °C to 85 °C and is typically available from authorized distributors with lead times of 4 to 12 weeks in normal supply conditions. Procurement teams requiring broader bandwidth or higher accuracy may evaluate the LTC1966 or LTC1967 siblings, which share the same 8-pin MSOP footprint and are pin-compatible for drop-in qualification.
