LTC6655BHLS8-2.5#PBF

Overview

The LTC6655BHLS8-2.5#PBF is a precision bandgap voltage reference from Analog Devices, featuring a fixed 2.5V output with ±0.025% initial accuracy and a maximum temperature coefficient of 2ppm/°C. It operates within a supply range of 3V to 13.2V, requiring a minimum dropout of 500mV. The device provides ±5mA source/sink current capability and includes a low-power shutdown mode consuming less than 20µA. Packaged in an 8-lead hermetic LS8 ceramic LCC (5mm × 5mm), it is fully specified over the –40°C to 125°C operating temperature range.

Feature Summary

High stability hermetic 5mm × 5mm LS8 package ensures outstanding long-term stability and eliminates humidity sensitivity.
Advanced curvature compensation achieves ultra-low drift of less than 2ppm/°C for high-precision applications.
Capable of sourcing and sinking up to ±5mA load current with superior line and load regulation.
Includes a dedicated shutdown pin for power reduction, drawing less than 20µA when disabled.

Applications

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

Procurement Notes

Verify the specific LS8 package designation and B grade accuracy suffix when ordering. Confirm that the hermetic ceramic construction meets environmental requirements for automotive or industrial use. Ensure the 5mm × 5mm footprint aligns with PCB layout constraints. Check for any recent product change notifications regarding assembly origin or material composition updates.

Selection Notes

Select this part for applications demanding minimal thermal drift and high long-term stability without calibration. The LS8 package is preferred over MSOP for harsh environments due to its hermetic seal and lack of humidity sensitivity. Consider the 500mV dropout requirement against available supply headroom. Evaluate the ±5mA drive capability against load demands to ensure stable operation under varying conditions.

Part Context

This component belongs to the LTC6655 family of precision voltage references, designed for high-resolution measurements. The LS8 variant specifically offers enhanced stability compared to standard plastic packages. It complements other Analog Devices signal chain components by providing a stable reference for ADCs and DACs in demanding environments.
