LT6658BIDE-5#PBF

Overview

The LT6658BIDE-5#PBF is a precision dual output voltage reference from Analog Devices, packaged in a 16-lead DFN. It provides a fixed 5V output with an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device operates within a junction temperature range of -40°C to +85°C and supports a maximum input voltage of 36V. Output 1 delivers up to 150mA sourcing current, while Output 2 provides up to 50mA.

Feature Summary

• Dual independent outputs with identical precision specifications that track each other over temperature and load variations
• Integrated Refulator architecture combining high-current linear regulation with low-noise voltage referencing capabilities
• Kelvin sense connections on outputs to achieve minimal load regulation errors under heavy loading conditions

Applications

• Driving reference inputs of high-resolution ADCs and DACs under heavy loading
• Powering microcontrollers and other circuitry simultaneously with analog signal chains
• Precision data acquisition systems requiring stable dual supply rails
• Automotive control and monitoring applications

Procurement Notes

Verify the specific suffix #PBF indicates RoHS compliance when ordering. Confirm the package type matches the design footprint requirements for the 16-lead DFN configuration. Ensure the B-grade performance specifications align with the system accuracy budget before finalizing procurement decisions.

Selection Notes

Select this component when dual isolated outputs are required for simultaneous digital and analog power domains. The B-grade offers a balance of cost and performance suitable for general precision applications. Consider the A-grade variant if tighter accuracy or lower drift specifications are necessary for the target application.

Part Context

This part belongs to the LT6658 family of precision dual output references. It shares the same core architecture as other variants but differs in output voltage, accuracy grade, and package style. The IDE designation specifically identifies the 16-lead DFN package option within the product line.
