Frequently Asked Questions
How does the LTC1967IMS8#TR's 390 µA supply current benefit battery-powered RMS measurement designs?
The LTC1967IMS8#TR's 390 µA quiescent current allows extended battery runtime in portable true-RMS measurement devices. Combined with a 4 MHz input signal bandwidth and 0.15% max linearity error, it supports accurate AC waveform measurement across a wide frequency range in handheld multimeters and energy logging instruments.
What waveform types can the LTC1967IMS8#TR accurately measure, and what crest factor does it support?
The LTC1967IMS8#TR uses delta-sigma architecture to accurately convert sinusoidal, distorted, and pulsed AC waveforms to a true-RMS DC output. It handles crest factors greater than 10 at signal amplitudes up to 1 V RMS, making it reliable for power quality analysis and non-sinusoidal waveform measurement in industrial instruments.
When is LTC1967IMS8#TR preferable to a diode-based rectifier circuit for AC signal measurement?
The LTC1967IMS8#TR outperforms diode rectifiers when accuracy matters — its 0.15% typical linearity error versus greater than 5% for diode circuits means far lower measurement error at full scale. Operating from ±2.25 V to ±5.5 V supply rails across -40°C to +85°C, it computes true-RMS for non-sinusoidal signals without temperature recalibration.
