LTC6655CHMS8-5#PBF

Overview

The LTC6655CHMS8-5#PBF is a precision bandgap voltage reference from Analog Devices, offering an output of 5V with ±0.05% initial accuracy and a maximum temperature coefficient of 5ppm/°C. It operates within a –40°C to 125°C range and supports a supply voltage up to 13.2V. The device features low dropout operation starting at VOUT + 0.2V under zero load, providing ±5mA source/sink current capability. Packaged in an 8-lead MSOP, it includes a shutdown mode consuming less than 20µA.

Feature Summary

• Advanced curvature compensation ensures predictable temperature characteristics and high accuracy.
• Capable of sourcing and sinking current for flexible load regulation requirements.
• Includes a dedicated shutdown pin for significant power reduction in standby modes.

Applications

• High resolution data acquisition systems
• Precision battery monitors
• Medical equipment

Procurement Notes

Verify the specific suffix CHMS8-5#PBF against official documentation to confirm the 5V output option and C-grade accuracy. Ensure the procurement channel provides genuine Analog Devices components to maintain specified performance levels. Confirm package type matches the 8-lead MSOP requirement for your design constraints.

Selection Notes

Select this component when a fixed 5V precision reference is required with moderate drift specifications. Consider the C-grade accuracy if calibration is feasible or unnecessary. Evaluate the MSOP package size against available board space. Verify that the input voltage remains within the specified operating range relative to the output voltage.

Part Context

This part belongs to the LTC6655 family of low noise, low drift precision references. It shares architectural similarities with other members like the LTC6655BHMS8-5 but offers different accuracy grades. The family is designed for demanding automotive and industrial applications requiring stable voltage references over wide temperature ranges.
