LTC6652BHMS8-5#PBF

Overview

The Analog Devices LTC6652BHMS8-5#PBF is a precision buffered voltage reference providing a fixed 5V output. It features B-grade initial accuracy of ±0.1% and a maximum temperature coefficient of 10ppm/°C. The device operates within a supply range of 2.7V to 13.2V, drawing 350µA typical quiescent current. It supports ±5mA source/sink currents and includes a shutdown mode consuming less than 2µA. Packaged in an 8-lead MSOP, it functions from -40°C to +125°C.

Feature Summary

• High-order curvature compensation ensures low drift with predictable temperature characteristics
• Capable of sourcing and sinking up to 5mA for demanding load conditions
• Operates with a minimum dropout voltage of 300mV above the output level
• Includes a low-power shutdown mode to minimize consumption when inactive

Applications

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

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 aligns with board layout constraints. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when a stable 5V reference is needed with high accuracy over wide temperature ranges. The B-grade specification suits applications tolerating ±0.1% initial error. Consider the 10ppm/°C drift limit against system thermal requirements. Verify that the 350µA supply current fits power budgets compared to lower-current alternatives.

Part Context

This part belongs to the LTC6652 family of precision, low-drift, low-noise references. The family offers various output voltages including 1.25V, 2.048V, 2.5V, 3V, 3.3V, 4.096V, and 5V. Variants include A-grade (±0.05%, 5ppm/°C) and B-grade options. Packages available are 8-lead MSOP and hermetic LS8.

Replacement Considerations

LTC6652AHMS8-5#PBF provides higher accuracy (±0.05%) and lower drift (5ppm/°C). LTC6652BHLS8-5#PBF uses a hermetic ceramic package with improved long-term stability.
