LTC6652AHLS8-4.096#PBF

Overview

The LTC6652AHLS8-4.096 is a precision buffered voltage reference with an output of 4.096V, housed in an 8-lead hermetic LS8 package. It features high accuracy (±0.05% max) and low temperature drift (5ppm/°C max). The device operates from supply voltages up to 13.2V and supports ±5mA source/sink current. Key specifications include low noise (2.1ppmP-P), shutdown current under 2µA, and thermal hysteresis of 45ppm over the -40°C to 125°C range.

Feature Summary

• High order curvature compensation ensures predictable temperature characteristics and low drift.
• Hermetic 5mm x 5mm surface mount package provides outstanding stability against humidity and mechanical stress.
• Capable of sourcing and sinking current for demanding load conditions without requiring an output capacitor.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the LS8 designation corresponds to the hermetic ceramic LCC variant rather than the standard plastic MSOP version. Ensure the grade 'A' aligns with the necessary accuracy and drift specifications for the design.

Selection Notes

Select this component when long-term stability and immunity to environmental factors are critical. The hermetic LS8 package is preferred over plastic packages for applications exposed to varying humidity or severe thermal cycling. Verify that the input voltage range accommodates the system's supply variations while maintaining the minimum dropout requirement.

Part Context

This part belongs to the LTC6652 family of precision voltage references designed for high-performance industrial and automotive environments. The LS8 package variant specifically addresses stability concerns associated with plastic molding compounds by utilizing a hermetic seal. It complements other components in precision signal chains where reference integrity dictates overall system accuracy.
