LT6660HCDC-2.5#TRMPBF

Overview

The LT6660HCDC-2.5#TRMPBF is a micropower series voltage reference from Analog Devices, housed in a 3-lead 2mm × 2mm × 0.75mm DFN package. It provides a fixed output of 2.5V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 20ppm/°C. The device operates within a supply voltage range of VOUT + 0.9V to 20V, drawing a typical supply current of 115µA at 25°C. It guarantees a sourcing output current up to 20mA and includes reverse-battery protection.

Feature Summary

• Curvature compensation and laser-trimmed thin-film resistors ensure high precision and low drift.
• Eliminates the need for an external output compensation capacitor.
• Reverse-battery protection prevents reverse current conduction.

Applications

• Handheld Instruments
• Precision Regulators
• A/D and D/A Converters

Procurement Notes

Verify the specific HC grade suffix against official datasheets to confirm the 0.2% accuracy and 20ppm/°C temperature coefficient specifications. Ensure the DFN-3 package dimensions align with PCB layout requirements. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when space constraints require a 2mm × 2mm footprint without sacrificing precision. It serves as a direct replacement for larger packages like the LT1460 while maintaining comparable performance metrics. Evaluate thermal management needs, as junction temperature impacts hysteresis and long-term stability.

Part Context

This part belongs to the LT6660 family of tiny micropower precision series references. The 'H' designation indicates the highest accuracy grade (±0.2%) within the product line. The '#TRMPBF' suffix denotes lead-free tape and reel packaging suitable for surface-mount assembly processes.
