LT6657AHMS8-2.5#TRPBF

Voltage Reference Overview

The LT6657AHMS8-2.5#TRPBF is a precision buffered voltage reference featuring an output voltage of 2.5V and an initial accuracy of ±0.1%. It exhibits a maximum temperature coefficient of 1.5ppm/°C for the A grade, with low noise performance of 0.5ppm P-P (0.1Hz to 10Hz) and 0.8ppm RMS (10Hz to 1kHz). The device operates within a supply range from VOUT + 50mV up to 40V, providing ±10mA output drive capability. It includes reverse battery protection, thermal shutdown, and a low-power shutdown mode consuming less than 4µA. The component is housed in an 8-lead MSOP package and is specified over a temperature range of –40°C to 125°C.

Voltage Reference Feature Summary

• Advanced curvature compensation technology ensures extremely low drift and predictable temperature behavior.
• Buffered output stage supports bidirectional current sourcing and sinking with low output impedance.
• Integrated reverse supply and output protection mechanisms safeguard against short circuits and overload conditions.
• Dedicated shutdown pin enables rapid turn-on and significantly reduces power consumption during inactive periods.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the specific 'A' grade designation matches the design requirement for the 1.5ppm/°C maximum temperature coefficient specification. Ensure compatibility with the 8-lead MSOP footprint dimensions during PCB layout verification.

Voltage Reference Selection Notes

Select this component when application requirements demand ultra-low drift characteristics combined with high load regulation capabilities. The wide input voltage range allows operation even when the supply rail is very close to the output voltage. Consider the bidirectional drive capability if the design requires the reference to source or sink significant load currents without external buffering components.

Voltage Reference Part Context

This part belongs to the LT6657 family of precision voltage references manufactured by Analog Devices Inc. The family utilizes advanced bandgap architecture to achieve industry-leading stability metrics. Variants within the series offer different fixed output voltages and packaging options, but share the core low-noise and low-drift performance characteristics defined by the base model specifications.
