LTC6652BHLS8-2.5#PBF

Overview

The LTC6652BHLS8-2.5#PBF is a precision buffered voltage reference featuring a fixed 2.5V output in an 8-lead hermetic LS8 package. It delivers high accuracy with ±0.1% initial tolerance and a maximum temperature coefficient of 8ppm/°C across the –40°C to 125°C range. The device supports up to 13.2V input, offers low noise (2.1ppm P-P), and includes a shutdown mode consuming less than 2µA.

Feature Summary

• High-order curvature compensation ensures predictable temperature characteristics and minimal drift over wide thermal ranges.
• Hermetic 5mm × 5mm surface mount construction provides outstanding long-term stability and immunity to humidity-induced stress shifts.
• Integrated buffer allows sourcing and sinking current while maintaining exceptional line rejection and load regulation.

Applications

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

Procurement Notes

Verify the LS8 package designation against standard MSOP variants to ensure correct form factor selection. Confirm that the B-grade specifications align with project requirements for initial accuracy and temperature drift limits before finalizing procurement.

Selection Notes

Select this component when hermetic sealing is required to prevent humidity-related performance degradation. The LS8 package offers superior thermal hysteresis performance compared to plastic packages, making it suitable for environments demanding extreme long-term stability.

Part Context

This part belongs to the LTC6652 family of precision references. While other variants utilize plastic MSOP packaging, the LS8 option specifically addresses applications requiring hermetic protection and enhanced mechanical stability against board assembly stresses.
