LTC6655BHLS8-5#PBF

Overview

The LTC6655BHLS8-5#PBF is a precision bandgap voltage reference from Analog Devices, offering an output of 5V with ±0.025% initial accuracy and a maximum drift of 2ppm/°C. It operates within a temperature range of –40°C to 125°C and supports a maximum supply voltage of 13.2V. The device features low dropout capability of 500mV, shutdown current below 20µA, and load regulation under 15ppm/mA. Packaged in a hermetic 8-lead LS8 (5mm × 5mm) ceramic LCC, it provides high stability for demanding applications.

Feature Summary

• Hermetic 8-lead LS8 package ensures long-term stability and eliminates humidity sensitivity
• Advanced curvature compensation achieves ultra-low drift and high accuracy without calibration
• Capable of sourcing and sinking up to 5mA with superior load regulation
• Low power shutdown mode reduces consumption to less than 20µA

Applications

• Instrumentation and test equipment
• High resolution data acquisition systems
• Precision battery monitors
• Medical equipment

Procurement Notes

Verify the specific LS8 package variant against design requirements due to its hermetic nature. Confirm that the 5V output option matches the system voltage needs. Ensure the PCB footprint aligns with the 5mm × 5mm leadless chip carrier dimensions. Check for any specific handling instructions related to the ceramic package during assembly.

Selection Notes

Select this part when extreme long-term stability and humidity resistance are critical, as provided by the LS8 package. Choose over MSOP variants if hermetic sealing is required for harsh environments. Consider the 2ppm/°C drift specification for high-precision applications where calibration is difficult or undesirable. Verify that the 5V output meets the target reference voltage requirements.

Part Context

This component belongs to the LTC6655 family of precision references, designed for high-resolution measurements. The LS8 package distinguishes it from standard plastic MSOP versions by offering a hermetic seal. This family utilizes advanced bandgap technology to deliver low noise and drift performance suitable for automotive and industrial sectors operating across wide temperature ranges.
