LTC6652AHMS8-2.5#TRPBF

Overview

The LTC6652AHMS8-2.5#TRPBF is a precision buffered voltage reference with a fixed output of 2.5V and an initial accuracy of ±0.05%. It features a maximum temperature coefficient of 5ppm/°C and operates over a –40°C to 125°C range. The device supports a supply voltage up to 13.2V, draws 350µA typical current, and provides ±5mA source/sink capability. It utilizes an 8-lead MSOP package.

Feature Summary

• High-order curvature compensation ensures low drift and predictable temperature characteristics
• Capable of sourcing and sinking current for demanding load conditions
• Includes a shutdown mode to minimize power consumption when inactive

Applications

• Automotive control and monitoring systems
• High-resolution data acquisition systems
• Precision regulators and instrumentation

Procurement Notes

Verify the specific A-grade performance parameters against the official datasheet specifications. Confirm that the TRPBF suffix indicates tape and reel packaging suitable for automated assembly processes. Ensure the component meets RoHS compliance requirements for your manufacturing environment.

Selection Notes

Select this part for applications requiring high stability and low noise in a compact surface mount form factor. Consider the 5ppm/°C drift specification for environments with significant thermal variations. Evaluate the 300mV dropout voltage to ensure adequate headroom between the input supply and the 2.5V output.

Part Context

This component belongs to the LTC6652 family of precision references from Analog Devices. The family includes variants with different output voltages and grades. The MSOP package offers a compact solution compared to hermetic LS8 options while maintaining robust performance across industrial and automotive temperature ranges.

Replacement Considerations

Identified substitutes include the LTC6652BHMS8-2.5#TRPBF, which shares the same package but has a B-grade temperature coefficient of 10ppm/°C and ±0.1% accuracy.
