LT6658BIMSE-3#TRPBF

Overview

The LT6658BIMSE-3#TRPBF is a precision dual output voltage reference from Analog Devices, housed in a 16-lead MSOP package. It provides a fixed 3V output with an initial accuracy of ±0.1% and a temperature coefficient of 20ppm/°C. The device operates within a junction temperature range of -40°C to 85°C and supports input voltages up to 36V. Output 1 delivers up to 150mA sourcing current, while Output 2 provides up to 50mA. Both outputs feature Kelvin sense connections for high load regulation.

Feature Summary

• Combines precision voltage reference and linear regulator performance
• Dual outputs track each other over temperature and load variations
• Kelvin sense connection ensures low load regulation error
• Separate supply pins allow power consumption reduction

Applications

• Driving precision reference inputs of high resolution ADCs and DACs
• Powering microcontrollers and supporting circuitry
• Data acquisition systems requiring stable references
• Automotive control and monitoring applications

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the B-grade specifications match system requirements for accuracy and drift. Ensure the MSOP-16 footprint aligns with PCB layout constraints. Check for RoHS compliance status if required by manufacturing standards.

Selection Notes

Select this part for applications needing two independent but tracking voltage rails from a single component. The B-grade offers standard precision suitable for general instrumentation. Consider the A-grade variant if tighter accuracy or lower drift is necessary. Verify thermal management capabilities given the exposed pad requirement for heat dissipation.

Part Context

This component belongs to the LT6658 family of Refulators™, designed to replace separate reference and regulator circuits. It simplifies board design by integrating dual buffered outputs. The MSOP package provides a compact solution for space-constrained designs compared to larger DFN options.

Replacement Considerations

LT6658AIMSE-3#TRPBF offers higher grade specifications (A-grade). LT6658BIDE-3#TRPBF provides the same electrical performance in a DFN-16 package.
