LTC6652BHMS8-4.096#PBF

Overview

The Analog Devices LTC6652BHMS8-4.096#PBF is a precision buffered voltage reference delivering a fixed 4.096V output. It features B-grade initial accuracy of ±0.1% and a maximum temperature coefficient of 10ppm/°C. The device operates from a supply voltage up to 13.2V with a minimum dropout of 300mV. It provides ±5mA source and sink current capability, low noise of 2.8ppm P-P (0.1Hz to 10Hz), and includes a shutdown mode consuming less than 2µA. Packaged in an 8-lead MSOP, it functions reliably across a –40°C to 125°C temperature range.

Feature Summary

• High-order curvature compensation ensures predictable temperature characteristics and low drift over the full operating range.
• Integrated buffer amplifier allows for robust source and sink current handling without external components.
• Low power shutdown mode significantly reduces consumption when the reference is inactive.
• Stable operation is maintained with or without an optional output capacitor.

Applications

• Automotive control and monitoring systems
• High resolution data acquisition systems
• Instrumentation and process control equipment
• Precise regulator circuits

Procurement Notes

Verify the specific B-grade performance parameters against the official datasheet specifications before integration. Confirm that the 8-lead MSOP package dimensions align with the target PCB footprint. Ensure the input supply voltage remains within the 13.2V absolute maximum rating during all operational conditions.

Selection Notes

Select this component when a stable 4.096V reference is required for high-precision applications. The B-grade specification offers a balance of cost and performance suitable for industrial environments. Consider the thermal resistance of the MSOP package if significant power dissipation is expected under heavy load conditions.

Part Context

This part belongs to the LTC6652 family of precision references, which are designed for demanding applications requiring low drift and low noise. The family includes various output voltages and grades, with the LS8 hermetic package offering enhanced stability for extreme environments compared to the standard plastic MSOP option.

FAQ

Is an output capacitor required for the LTC6652BHMS8-4.096?

No, the device is stable with or 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.
