LTC6655CHMS8-2.5#TRPBF

Overview

The LTC6655CHMS8-2.5#TRPBF is a precision bandgap voltage reference from Analog Devices, featuring a fixed 2.5V output with ±0.05% initial accuracy and a maximum temperature coefficient of 5ppm/°C. It operates within a supply voltage range of 3V to 13.2V, drawing a typical quiescent current of 7.5mA. The device provides ±5mA sourcing and sinking capability with low dropout performance. Packaged in an 8-lead MSOP, it supports a wide operating temperature range from –40°C to +125°C.

Feature Summary

• Advanced curvature compensation ensures predictable temperature characteristics and high accuracy.
• Capable of both sourcing and sinking load currents for superior regulation under varying conditions.
• Includes a dedicated shutdown mode to minimize power consumption in low-power applications.

Applications

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

Procurement Notes

Verify the specific 'C' grade suffix against official documentation to confirm the 5ppm/°C temperature coefficient and ±0.05% accuracy specifications. Ensure the ordering suffix matches the required tape and reel packaging format. Confirm that the 8-lead MSOP package aligns with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when moderate drift performance is acceptable alongside low noise requirements. The CH grade offers a balance between cost and precision. Verify that the 3V minimum input voltage requirement fits your system's headroom constraints relative to the 2.5V output.

Part Context

This part belongs to the LTC6655 family of precision references designed for high-resolution measurements. It utilizes advanced curvature compensation to achieve low drift without calibration. The family includes various output voltages and packages, such as the hermetic LS8, to suit different environmental and stability needs.
