LTC6652BHMS8-2.048#PBF

Voltage Reference Overview

The LTC6652BHMS8-2.048#PBF is a precision buffered voltage reference with a fixed output of 2.048V, housed in an 8-lead MSOP package. It features B-grade initial accuracy of ±0.1% and a maximum temperature coefficient of 10ppm/°C over the –40°C to 125°C range. The device operates from supply voltages up to 13.2V with a minimum dropout of 300mV or 2.7V total supply. Key electrical parameters include a typical supply current of 350µA, shutdown current under 2µA, and low-frequency noise of 2.1ppm P-P (0.1Hz to 10Hz).

Voltage Reference Feature Summary

• High-order curvature compensation ensures predictable temperature characteristics and low drift.
• Capable of sourcing and sinking significant load currents without requiring external capacitors for stability.
• Includes a dedicated shutdown pin that reduces power consumption when the reference is inactive.
• Offers exceptional line rejection and excellent load regulation for demanding precision applications.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging. Confirm the 'B' grade designation matches the required ±0.1% accuracy and 10ppm/°C drift specifications. Ensure the MSOP-8 package footprint aligns with the PCB layout requirements. Check for any RoHS compliance documentation if environmental regulations apply to the final assembly.

Voltage Reference Selection Notes

Select this component when a stable 2.048V reference is needed for high-performance industrial or automotive environments. The B-grade specification provides a balance of cost and performance for applications tolerating ±0.1% initial accuracy. Consider the MSOP-8 package for standard surface-mount assembly processes where hermetic LS8 packages are not required.

Voltage Reference Part Context

This part belongs to the LTC6652 family of precision, low-drift, low-noise references. The family includes A-grade and B-grade options across various output voltages such as 1.25V, 2.5V, and 5V. The MSOP package variant offers a compact plastic solution suitable for general-purpose high-temperature applications within the specified operating range.

Voltage Reference Replacement Considerations

LTC6652AHMS8-2.048#PBF: Offers tighter A-grade specifications including ±0.05% accuracy and 5ppm/°C drift while maintaining the same package and functionality.
