LTC6652BHMS8-2.5#PBF

Overview

The LTC6652BHMS8-2.5#PBF is a precision buffered voltage reference with a fixed output of 2.5V and an initial accuracy of ±0.1%. It features a maximum temperature coefficient of 10ppm/°C and operates over a –40°C to 125°C range. The device supports a supply voltage up to 13.2V, draws 350µA at no load, and provides ±5mA source/sink current. It includes a shutdown mode consuming less than 2µA and is housed in 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
• Operates with minimal dropout voltage relative to the output level
• Includes a low-power shutdown mode to reduce 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 B-grade performance parameters against the official datasheet before integration. Confirm that the MSOP-8 package dimensions match the target PCB footprint. Ensure the input voltage remains within the specified limits to maintain line regulation. Check for any recent product change notices regarding marking or packaging updates.

Selection Notes

Select this component when high stability is required across wide temperature ranges. The B-grade offers a balance of cost and performance for industrial applications. Consider the LS8 package if hermetic sealing is necessary for extreme environments. Evaluate power dissipation limits if operating near maximum input voltages.

Part Context

This part belongs to the LTC6652 family of precision references designed for automotive and high-performance industrial use. The family utilizes high-order curvature compensation to achieve superior thermal stability. Other variants in the series provide different fixed output voltages while maintaining similar low-noise and low-drift specifications.

FAQ

Is an external output capacitor required for stability?

No, the LTC6652 is stable without an output capacitor. However, adding a capacitor between 0.1µF and 10µF can be beneficial for specific load conditions.

How does the shutdown pin function?

Tying the SHDN pin low powers down the device to less than 2µA. For normal operation, the pin should be tied to VIN or driven high.
