LT6657AHMS8-5#TRPBF

Voltage Reference Overview

The LT6657AHMS8-5#TRPBF is a precision buffered voltage reference with a fixed 5V output, housed in an 8-lead MSOP package. It features an initial accuracy of 0.1% and a maximum temperature coefficient of 1.5ppm/°C. The device operates over a supply range from VOUT + 50mV to 40V, supporting a minimum input-to-output differential of 50mV. It provides ±10mA drive capability with low output impedance. Key electrical parameters include 0.2ppm/V line regulation and 2µV/mA load regulation.

Voltage Reference Feature Summary

• Advanced curvature compensation for extremely low drift and predictable temperature behavior
• Buffered output stage capable of sourcing and sinking current with high precision
• Integrated reverse battery protection, short-circuit protection, and thermal shutdown
• Configurable as a negative voltage reference or operated in shunt mode

Voltage Reference 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

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube. Confirm the 'A' grade designation matches the required 1.5ppm/°C temperature coefficient specification. Ensure the pinout corresponds to the standard MSOP-8 configuration for your PCB layout.

Voltage Reference Selection Notes

Select this part when a fixed 5V output is required alongside robust operating characteristics. Consider the wide supply range up to 40V and the ability to operate with minimal dropout voltage. Evaluate the low noise performance for sensitive analog front ends and verify compatibility with the required shutdown logic levels.

Voltage Reference Part Context

This component belongs to the LT6657 family of precision voltage references manufactured by Analog Devices. The series combines bandgap technology with buffering to deliver high stability.

Voltage Reference FAQ

Can the LT6657 be used as a negative voltage reference?

Yes, the high sink current capability allows it to operate as a negative voltage reference with the same precision as a positive reference.

What is the minimum input-to-output voltage differential?

The device can be powered from as little as 50mV above the output voltage.
