**LTC1968CMS8#PBF: A True RMS-to-DC Converter in MSOP-8 Package**

The accurate measurement of complex waveforms is a critical requirement across numerous electronic applications, from power monitoring to audio processing. While average-responding converters are common, they introduce significant errors when faced with non-sinusoidal signals. The **LTC1968CMS8#PBF** from Analog Devices addresses this fundamental challenge, delivering **high accuracy true RMS-to-DC conversion** in a remarkably compact MSOP-8 package.

This innovative integrated circuit utilizes a proprietary **delta-sigma computational technique** to calculate the true RMS value of an input signal. Unlike traditional log-antilog or implicit methods, this approach is inherently more linear and accurate, requiring no external scaling components or special laser-trimming during manufacturing. The device operates over a wide input bandwidth, effectively handling signals with high crest factors, which is a key indicator of its ability to accurately measure the RMS value of noisy or peaky waveforms that would baffle simpler converters.

A standout feature of the LTC1968 is its **exceptional ease of use**. It requires a minimal number of external components—essentially just a single bypass capacitor—to form a complete RMS measurement solution. This simplicity drastically reduces design time and board space. Furthermore, it is designed for low power consumption, making it an ideal choice for portable and battery-powered instrumentation. The converter accepts input signal levels up to 1V RMS and provides a DC output that is linearly proportional to the input's RMS value, with outstanding accuracy over a specified temperature range.

Housed in an **MSOP-8 package**, the LTC1968CMS8#PBF exemplifies the trend of packing high-performance analog functionality into tiny form factors. This makes it perfectly suited for space-constrained applications such as handheld multimeters, HVAC systems, vibration analysis equipment, and automotive sensor interfaces. Its robust performance and small footprint allow designers to incorporate professional-grade metrology into modern, miniaturized products without compromising on measurement integrity.

**ICGOOODFIND**: The LTC1968CMS8#PBF is a pinnacle of analog innovation, providing a simple, precise, and robust solution for true RMS measurement. Its delta-sigma computation core, minimal external component count, and ultra-small MSOP-8 package make it an unparalleled choice for designers seeking to add accurate power and signal measurement capabilities to their advanced electronic systems.
