LTC6655LNBHMS8-4.096#TRPBF

Overview

The LTC6655LNBHMS8-4.096#TRPBF is a low noise precision bandgap voltage reference with a fixed output of 4.096V and an initial accuracy of ±0.025%. It features a maximum temperature coefficient of 2ppm/°C and operates over a –40°C to 125°C range. The device includes a dedicated noise reduction pin for filtering wideband noise using a single capacitor. It supports a supply voltage up to 13.2V, requires a minimum dropout of 500mV, and provides ±5mA source/sink current capability in an 8-lead MSOP package.

Feature Summary

• Advanced curvature compensation ensures predictable drift characteristics below 2ppm/°C across the full operating temperature range.
• Integrated noise reduction pin allows for significant wideband noise attenuation by connecting a single external capacitor.
• Dual-output architecture enables remote sensing via a dedicated sense pin to minimize load regulation errors caused by trace resistance.
• Capable of sourcing and sinking up to ±5mA while maintaining exceptional line rejection and consistent performance under varying loads.

Applications

• High resolution data acquisition systems
• Precision instrumentation and test equipment
• Medical equipment requiring stable references
• Precision battery monitors

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the 'LN' designation corresponds to the low noise variant with the noise reduction pin. Ensure the 'B' grade matches the required ±0.025% initial accuracy specification. Check that the MSOP-8 package aligns with the target PCB footprint constraints.

Selection Notes

Select this component when ultra-low noise and high stability are critical for signal integrity. The LN variant is preferred over standard versions for applications sensitive to wideband interference. Consider the remote sense pin if long traces connect the reference to the load. Verify that the 4.096V output level fits the input requirements of the downstream analog-to-digital converter or amplifier stage.
