LT6657BHMS8-4.096#PBF

Overview

The LT6657BHMS8-4.096#PBF is a precision buffered voltage reference with an output of 4.096V and initial accuracy of 0.1%. It features a maximum temperature drift of 3ppm/°C, line regulation of 4ppm/V, and load regulation of 15µV/mA. The device operates from –40°C to 125°C with a supply range up to 40V and dropout as low as 50mV. It provides ±10mA drive current, includes reverse polarity protection, thermal shutdown, and a low-power shutdown mode consuming less than 4µA.

Feature Summary

Advanced curvature compensation for extremely low drift and predictable temperature behavior
Buffered output capable of sourcing and sinking 10mA with high precision load regulation
Incorporates reverse battery protection, short-circuit protection, and thermal shutdown
Configurable for negative voltage reference operation or shunt mode applications

Applications

High resolution data acquisition systems
Instrumentation and process control
Automotive control and monitoring
Medical equipment
Shunt and negative voltage references

Procurement Notes

Verify the specific B-grade temperature coefficient of 3ppm/°C against system requirements. Confirm the MSOP-8 package dimensions match the PCB footprint. Ensure input capacitors are placed close to the pins to maintain stability and power supply rejection ratio performance.

Selection Notes

Select this part when a 4.096V output is required with strict drift limits under moderate temperature variations. The B-grade offers a balance between cost and performance compared to the A-grade. Consider the low dropout capability if the supply voltage is close to the output level.

Part Context

This component belongs to the LT6657 family of ultra-stable bandgap voltage references manufactured by Analog Devices. The series is designed for demanding applications requiring robust operating characteristics combined with low noise and low drift in a compact surface-mount package.

Replacement Considerations

LT6657AHMS8-4.096#PBF (A-Grade, 1.5ppm/°C drift)

FAQ

Can the LT6657BHMS8-4.096#PBF operate as a negative voltage reference?

Yes, the high sink current capability allows it to be configured as a negative voltage reference while maintaining the same precision as positive reference operation.
