LT6657BHMS8-5#PBF

Overview

The LT6657BHMS8-5#PBF is a precision buffered voltage reference with a fixed 5V output. It features an initial accuracy of 0.1% and a maximum temperature coefficient of 3ppm/°C. The device supports a wide supply range up to 40V and operates within a temperature range of –40°C to 125°C. It provides ±10mA drive capability, low noise performance, and includes reverse polarity protection.

Feature Summary

• Advanced curvature compensation for extremely low drift
• Buffered output supporting bidirectional current sourcing and sinking
• Integrated reverse supply and output protection mechanisms
• Low power shutdown mode with rapid turn-on capability

Applications

• High resolution data acquisition systems
• Instrumentation and process control circuits
• Automotive control and monitoring applications
• Medical equipment requiring stable references
• Shunt and negative voltage reference configurations

Procurement Notes

Verify the B grade designation ensures compliance with the 3ppm/°C maximum temperature coefficient specification. Confirm the MSOP-8 package type matches the PCB footprint requirements. Ensure the #PBF suffix indicates RoHS and WEEE compliance status as required by project specifications.

Selection Notes

Select this component when a 5V output is required alongside high stability over wide temperature variations. The B grade offers a balance of cost and performance suitable for industrial environments. Consider the low dropout characteristics if operating near minimum supply voltages or in shunt mode configurations.
