LT6658AIDE-2.5#PBF

Overview

The LT6658AIDE-2.5#PBF is a precision dual output voltage reference from Analog Devices, featuring a fixed 2.5V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. It operates within a junction temperature range of -40°C to +85°C and accepts input voltages up to 36V. The device utilizes a 16-lead DFN package (4mm × 3mm) with an exposed thermal pad for heat dissipation.

Feature Summary

• Combines the performance of a precision voltage reference and a linear regulator in a single component
• Provides two independent outputs that track each other over temperature and load variations
• Features Kelvin sense connections on outputs to minimize load regulation errors under heavy loading conditions

Applications

• Driving reference inputs of high resolution ADCs and DACs
• Powering microcontrollers and supporting circuitry
• Data acquisition systems requiring stable voltage references

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and operating temperature range. Ensure compatibility with PCB layout requirements for the DFN exposed pad connection. Confirm RoHS compliance status through manufacturer datasheets before procurement.

Selection Notes

Select this part when dual isolated outputs are required for simultaneous analog and digital supply needs. Consider the A-grade specifications for applications demanding tighter accuracy and lower drift compared to B-grade alternatives. Evaluate thermal management requirements based on the DFN package characteristics.

Part Context

This component belongs to the LT6658 family of Refulator devices designed for high-performance data conversion systems. It integrates low noise and low drift capabilities into a compact surface-mount package suitable for space-constrained designs requiring precise voltage regulation.

Replacement Considerations

LT6658BIDE-2.5#PBF offers similar functionality with relaxed accuracy and temperature coefficient specifications.
