LTC6655LNBHMS8-5#TRPBF

Overview

The LTC6655LNBHMS8-5#TRPBF is a precision bandgap voltage reference from Analog Devices, offering a fixed 5V output with ±0.025% initial accuracy and a maximum temperature coefficient of 2ppm/°C. It operates within a supply voltage range of VOUT + 0.5V to 13.2V and features low power shutdown current below 20µA. The device provides ±5mA source and sink capability with superior load regulation. Packaged in an 8-lead MSOP, it includes a dedicated noise reduction pin for wideband noise suppression.

Feature Summary

• Features a dedicated noise reduction pin that enables significant wideband noise reduction through the addition of a single external capacitor.
• Provides high accuracy with ±0.025% initial tolerance and advanced curvature compensation for drift less than 2ppm/°C.
• Supports both sourcing and sinking currents up to ±5mA with excellent line rejection and load regulation.
• Includes a low-power shutdown mode drawing less than 20µA, controlled by an active-low input.

Applications

• Instrumentation and test equipment
• High resolution data acquisition systems
• Precision battery monitors

Procurement Notes

Verify the specific 'LN' suffix indicates the Low Noise variant with the noise reduction pin when ordering. Confirm the package type matches the required PCB footprint, as this part is supplied in tape and reel format. Ensure the application circuit utilizes appropriate output capacitors to maintain stability and achieve specified performance metrics.

Selection Notes

Select this component for applications requiring high DC accuracy and low drift over a wide temperature range. The LN version is suitable where wideband noise reduction is critical without complex filtering. Consider the 5V output option if system architecture requires this specific rail. Verify thermal management requirements for the MSOP package under continuous operation.
