Overview
The LTC6652BHMS8-2.048#TRPBF is a precision buffered voltage reference delivering a fixed 2.048V 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 or 2.7V total supply, whichever is higher. It provides ±5mA source/sink current capability and includes a low-power shutdown mode drawing less than 2µA. The component is housed in an 8-lead MSOP package and is fully specified over the –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 significant load currents without requiring external buffering components.
- Operates stably with or without an optional output capacitor, accommodating space-constrained designs.
- Includes a dedicated shutdown pin to minimize power consumption during inactive periods.
Applications
- Automotive control and monitoring systems
- High-resolution data acquisition systems
- Precision regulators and instrumentation
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 voltage remains within the 13.2V absolute maximum rating to prevent device damage. Validate thermal dissipation requirements under maximum load conditions.
Selection Notes
Select this part for applications requiring a stable 2.048V reference with moderate precision. The B-grade specification suits general industrial uses where ±0.1% accuracy is sufficient. Consider the A-grade variant if tighter tolerance is required. Evaluate the MSOP package for standard surface mount assembly processes.
Part Context
This component belongs to the LTC6652 family of precision voltage references designed for demanding environments. The family offers various output voltages including 1.25V, 2.5V, and 5V options. The MSOP package provides a compact solution compared to hermetic LS8 alternatives, balancing size and performance for standard commercial and industrial applications.

FAQ
Is an external output capacitor required for stability?
No, the LTC6652 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 mode affect the output voltage?
When the SHDN pin is pulled low, the device enters a low-power state. The output impedance becomes approximately 20kΩ multiplied by the rated output voltage.
