LTC6652BHMS8-2.5#TRPBF

Overview

The LTC6652BHMS8-2.5#TRPBF is a precision buffered voltage reference with a fixed output of 2.5V and B-grade accuracy of ±0.1%. It features a maximum temperature coefficient of 10ppm/°C and low noise of 2.1ppm P-P in the 0.1Hz to 10Hz band. The device operates from a supply voltage up to 13.2V, requiring a minimum dropout of 300mV or 2.7V total. It provides ±5mA source and sink current capability and includes a shutdown mode consuming less than 2µA. The component is housed in an 8-lead MSOP package and is fully specified over a –40°C to 125°C operating range.

Feature Summary

• High-order curvature compensation ensures predictable temperature characteristics and low drift.
• Capable of sourcing and sinking current for demanding load regulation requirements.
• Shutdown mode significantly reduces power consumption when the reference is inactive.
• Stable operation without mandatory external load capacitors, though optional capacitance is supported.

Applications

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

Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the B-grade designation aligns with the specific accuracy and drift tolerances needed for the target application. Ensure the 8-lead MSOP footprint matches the PCB layout design. Cross-reference the manufacturer part number against official Analog Devices documentation to confirm active status and lead-free compliance specifications.

Selection Notes

Select this component when applications require a buffered output capable of driving moderate loads with both sourcing and sinking capabilities. The B-grade specification offers a balance of performance and cost for industrial environments. Consider the low dropout characteristic if the system operates near the minimum supply voltage threshold. Evaluate the thermal dissipation limits relative to the input voltage and load current to ensure operation within safe junction temperature ranges.

Part Context

This part belongs to the LTC6652 family of precision, low drift, and low noise references designed for high-temperature environments. The family utilizes high-order curvature compensation to achieve superior stability compared to standard bandgap references. The MSOP package variant provides a compact surface-mount solution suitable for space-constrained designs while maintaining robust electrical performance across the extended automotive temperature range.
