LTC6655CHMS8-1.25#PBF

Overview

The Analog Devices LTC6655CHMS8-1.25#PBF is a precision bandgap voltage reference providing a fixed 1.25V output with an initial accuracy of ±0.05%. It features a maximum temperature coefficient of 5ppm/°C and operates within a supply voltage range from VOUT + 0.5V up to 13.2V. The device draws a typical supply current of 7mA and supports sourcing and sinking currents of ±5mA. It includes a shutdown mode consuming less than 20µA and is housed in an 8-lead MSOP package, fully specified over the -40°C to 125°C temperature range.

Feature Summary

Advanced curvature compensation ensures predictable temperature characteristics and high accuracy, reducing or eliminating calibration requirements.
Superior load regulation combined with source and sink capability maintains consistent performance across wide operating conditions.
Low dropout design allows operation with minimal headroom above the output voltage, while a dedicated shutdown pin enables low-power applications.

Applications

Instrumentation and test equipment requiring high resolution measurements
High resolution data acquisition systems
Precision battery monitors

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing distributor listings. Confirm the 'C' grade designation corresponds to the required 5ppm/°C temperature coefficient and 0.05% initial accuracy for your design specifications. Ensure the MSOP-8 footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a fixed 1.25V reference is needed with moderate drift specifications. The CHMS8 variant offers a cost-effective solution compared to the B-grade or LS8 hermetic packages. Consider the 5ppm/°C drift if tighter stability is not critical, and verify that the 7mA supply current fits the system power budget.

Part Context

This part belongs to the LTC6655 family of precision voltage references designed for demanding automotive and industrial applications. The family includes options with lower noise (LTC6655LN) and higher accuracy grades (B-grade). The MSOP package provides a compact surface-mount solution suitable for space-constrained designs requiring stable voltage references.
