LT6658AIMSE-5#TRPBF

Overview

The LT6658AIMSE-5#TRPBF is a precision dual output voltage reference from Analog Devices, housed in a 16-lead MSOP package. It provides a fixed 5V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device operates within a junction temperature range of -40°C to +85°C and accepts input voltages up to 36V. Output 1 supports sourcing currents up to 150mA, while Output 2 supports 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 connections ensure accurate load regulation under heavy loading

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the A-grade designation matches the required accuracy and temperature coefficient specifications for your application. Ensure the MSOP-16 footprint aligns with your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when dual isolated or tracked supplies are needed for sensitive analog front ends. The A-grade specification ensures tighter tolerance limits compared to B-grade options. Consider the separate supply pins (VIN1, VIN2) if independent power management or noise isolation between outputs is required for the system architecture.

Part Context

This part belongs to the LT6658 family of Refulator™ devices, which integrate low-noise references with high-current buffers. The AIMSE variant specifically denotes the A-grade performance level within the MSOP-16 plastic package format. It is designed to replace standard LDOs where superior stability and lower noise are critical for signal integrity.

Replacement Considerations

LT6658BIMSE-5#TRPBF offers similar functionality with relaxed accuracy and drift specifications.
