LT1088CD

Overview

The LT1088CD is a wideband RMS-to-DC converter building block manufactured by Analog Devices Inc. It operates in a 14-pin ceramic dual in-line package (CDIP). The device provides accurate conversion of AC signals to DC voltage levels, maintaining bandwidth flatness over the input voltage range. It supports a 300 MHz -3dB bandwidth and offers high accuracy across varying frequencies, including 1% accuracy from DC to 50 MHz and 2% accuracy up to 100 MHz. The component handles crest factors up to 50:1 and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides wideband RMS-to-DC conversion capabilities for signal processing applications
• Maintains bandwidth flatness across the entire input voltage range
• Supports high crest factor inputs up to 50:1 ratio
• Delivers consistent accuracy performance across a broad frequency spectrum

Applications

• RF power measurement systems
• Audio signal analysis equipment
• Communication system monitoring circuits
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Confirm that the 14-CDIP package matches your PCB footprint requirements. Check current product status as legacy components may have limited availability or require alternative sourcing strategies for long-term production stability.

Selection Notes

Select this component when wideband frequency response is critical for RMS measurement accuracy. Ensure the application requires handling high crest factors without distortion. Verify that the through-hole mounting style fits the assembly constraints. Consider the operating temperature range suitability for the intended environmental conditions before finalizing the design choice.

Part Context
