LT6658BIDE-2.5#TRPBF

Overview

The LT6658BIDE-2.5#TRPBF is a precision dual output voltage reference from Analog Devices, featuring a fixed 2.5V output with ±0.1% initial accuracy and a maximum temperature coefficient of 20ppm/°C. It operates within a junction temperature range of -40°C to 85°C and utilizes a 16-lead (4mm × 3mm) DFN package. The device integrates two independent outputs capable of sourcing up to 150mA on Output 1 and 50mA on Output 2, while supporting an input voltage range up to 36V.

Feature Summary

• Dual output architecture with identical precision specifications that track each other over temperature and load variations
• Integrated Refulator technology combining high-current linear regulation with low-noise voltage referencing capabilities
• Kelvin sense connections enable precise load regulation by minimizing trace resistance effects
• Separate supply pins for each output allow independent power management and noise isolation

Applications

• Microcontroller or FPGA systems requiring simultaneous ADC/DAC reference supplies
• Data acquisition systems demanding high stability under heavy loading conditions
• Automotive control and monitoring circuits requiring robust thermal performance
• Precision instrumentation and process control equipment

Procurement Notes

Verify the specific B-grade performance parameters against system requirements before procurement. Confirm the DFN-16 package footprint compatibility with the PCB layout. Ensure the tape and reel packaging format aligns with automated assembly equipment specifications. Cross-reference the manufacturer's latest documentation for any potential revisions or obsolescence notices.

Selection Notes

Select this component when dual isolated references are required in a compact form factor. The B-grade specification offers a balance of cost and performance for general-purpose precision applications. Consider the separate supply pin configuration if independent power domain isolation is necessary to minimize cross-talk between sensitive analog sections.

Part Context

This part belongs to the LT6658 family of precision dual output references. It shares architectural similarities with MSOP variants but utilizes a DFN package for improved thermal dissipation. The family includes A-grade and H-grade options offering tighter tolerances and wider temperature ranges respectively.

Replacement Considerations

LT6658AIDE-2.5#TRPBF provides equivalent functionality with higher accuracy grades.
