LT6658BHMSE-5#PBF

Overview

The LT6658BHMSE-5#PBF is a precision dual output voltage reference from Analog Devices, featuring a fixed 5V output. It operates within a junction temperature range of -40°C to +125°C and utilizes a 16-lead MSOP package. The device provides an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. It supports a maximum input voltage of 36V with a typical operating supply current of 1.9mA.

Feature Summary

• Combines precision voltage reference performance with linear regulator capabilities for simultaneous high-resolution ADC/DAC driving and microcontroller powering
• Features Kelvin sense connections on outputs to achieve exceptional load regulation under heavy loading conditions
• Includes separate supply pins for each output to allow power consumption reduction and buffer amplifier isolation

Applications

• Microcontroller or FPGA systems requiring integrated ADC/DAC references
• Data acquisition systems demanding stable dual-rail supplies
• Automotive control and monitoring circuits
• Precision low noise regulators in instrumentation

Procurement Notes

Verify the specific suffix against official documentation to confirm the exact grade and package variant. Confirm RoHS compliance status through manufacturer datasheets. Check for availability constraints as distribution channels may report limited stock or special order requirements for this component.

Selection Notes

Select this part when a B-grade specification with 20ppm/°C drift is sufficient for the application. Ensure the system requires a fixed 5V output rather than adjustable options. Verify that the MSOP-16 footprint fits the PCB layout constraints and that the thermal management strategy accommodates the exposed pad requirement.

Part Context

This component belongs to the LT6658 family of Refulator devices. It shares architectural similarities with other grades like the AIMSE and AHMSE series but differs in temperature range and accuracy specifications. The H-grade designation specifically indicates the extended industrial temperature capability up to 125°C.

Replacement Considerations

LT6658AHMSE-5#PBF offers higher accuracy (A-grade) with the same temperature range and package.
