LT6660KCDC-10#TRPBF

Overview

The LT6660KCDC-10#TRPBF is a micropower series voltage reference from Analog Devices, featuring a fixed 10V output. It operates within an input voltage range of VOUT + 0.9V to 20V and delivers up to 20mA of load current. The device guarantees a maximum initial accuracy of 0.5% and a temperature coefficient of 50ppm/°C over the 0°C to 70°C specified range. Supply current is typically 270µA at this voltage setting. It utilizes curvature compensation and laser-trimmed thin-film resistors for precision.

Feature Summary

• Curvature compensated design with laser-trimmed thin-film resistors
• Reverse-battery protection prevents reverse current conduction
• Stable operation without requiring an output compensation capacitor
• Low IR reflow induced stress typical value of 0.02%

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates lead-free tape and reel packaging. Confirm the KCDC designation corresponds to the 0.5% accuracy grade and 50ppm/°C temperature coefficient. Ensure the DC package type matches the required footprint. Check for any obsolescence notices or limited supply status directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this part when a 10V fixed reference is needed in a compact 3-lead DFN package. It is suitable for applications prioritizing low power consumption and high accuracy over a standard industrial temperature range. Consider the 0.5% tolerance if system calibration is not feasible. Evaluate thermal management requirements as junction temperature affects hysteresis performance.

Part Context

This component 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. Different letter grades (H, J, K) denote varying levels of accuracy and temperature coefficient specifications. The DC package provides a space-saving alternative to larger packages like the LT1460.

Replacement Considerations

LT6660JCDC-10#TRPBF offers 0.4% accuracy and 20ppm/°C drift. LT6660HCDC-10#TRPBF provides 0.2% accuracy and 20ppm/°C drift. These are direct pin-compatible upgrades within the same family offering tighter tolerances.
