LT6660HCDC-10

Overview

The LT6660HCDC-10 is a micropower series voltage reference providing a fixed 10V output with 0.2% initial accuracy and a maximum temperature coefficient of 20ppm/°C. It operates within an input voltage range of VOUT + 0.9V to 20V, drawing a typical supply current of 270µA at 25°C. The device guarantees a 20mA output current and features reverse-battery protection. Packaged in a compact 3-lead 2mm × 2mm DFN, it eliminates the need for an output compensation capacitor.

Feature Summary

• Curvature compensation and laser-trimmed thin-film resistors ensure high precision and low drift.
• Reverse-battery protection prevents reverse current conduction.
• Capacitor-free operation enables fast settling times and minimal board space usage.

Applications

• Precision regulators
• A/D and D/A converters
• Handheld instruments

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and environmental rating. Confirm that the ordering suffix does not alter the electrical function or pinout. Ensure compatibility with the required operating temperature range and verify RoHS compliance status for the specific manufacturing batch.

Selection Notes

Select this component when a fixed 10V reference is required in a space-constrained design. It serves as a space-saving alternative to larger packages like the LT1460. Consider the 20ppm/°C drift and 0.2% accuracy limits against system requirements. Evaluate thermal management needs to prevent junction temperatures from exceeding 85°C during high-power dissipation.

Part Context

This part belongs to the LT6660 family of tiny micropower precision series references. The family offers various voltage options including 2.5V, 3V, 3.3V, 5V, and 10V. The 'H' grade denotes the highest accuracy tier (0.2%) within the series, distinguishing it from 'J' and 'K' grades which offer lower precision specifications.
