LTC6655LNCHMS8-5#PBF

Overview

The LTC6655LNCHMS8-5#PBF is a precision bandgap voltage reference from Analog Devices, featuring low noise and drift characteristics. It provides a fixed output voltage of 5V with an initial accuracy of ±0.025% and a maximum temperature coefficient of 2ppm/°C. The device operates within a supply voltage range of 3V to 13.2V and supports both sourcing and sinking currents up to ±5mA. It includes a shutdown mode consuming less than 20µA and is housed in an 8-lead MSOP package.

Feature Summary

• Low Noise: Features a dedicated noise reduction pin for wideband noise suppression using a single capacitor.
• High Accuracy: Offers exceptional initial accuracy and predictable temperature drift reducing calibration needs.
• Dual Output Capability: Provides separate force and sense pins for precise load regulation.
• Low Power Shutdown: Includes a shutdown mode for significant power savings in battery-operated systems.

Applications

• Instrumentation and Test Equipment
• High Resolution Data Acquisition Systems
• Precision Battery Monitors

Procurement Notes

Verify the specific suffix 'LN' indicates the low noise variant with a noise reduction pin. Confirm the 'CH' designation corresponds to the specified accuracy grade. Ensure the '#PBF' suffix matches the required tube packaging format rather than tape and reel options. Cross-reference the full part number against the manufacturer's current ordering information to confirm availability and lead times.

Selection Notes

Select this component when ultra-low noise performance is critical for high-resolution applications. The LTC6655LN variant is distinct from the standard LTC6655 due to its enhanced noise specifications. Consider the need for external capacitors on the noise reduction pin to achieve optimal performance. Evaluate the thermal management requirements given the operating temperature range and package type.

Part Context

This part belongs to the LTC6655 family of precision voltage references designed for demanding automotive and industrial environments. The family offers various output voltages and accuracy grades. The LN variant specifically targets applications requiring minimal noise interference. The MSOP package provides a compact solution for space-constrained designs.
