LT6658AHMSE-5#PBF

Voltage Reference Overview

The LT6658AHMSE-5#PBF is a precision dual output voltage reference from Analog Devices, operating at a nominal 5V. It features an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device supports a wide input voltage range up to 36V and operates within a junction temperature range of -40°C to 125°C. Output 1 provides sourcing current up to 150mA with sinking capability of 20mA, while Output 2 sources up to 50mA and sinks 20mA. It utilizes Kelvin sense connections for load regulation and includes thermal shutdown protection.

Voltage Reference Feature Summary

• Combines the performance of a precision voltage reference and a linear regulator in a single component.
• Features two independent outputs that track each other over temperature and load variations.
• Includes separate supply pins for each output to allow power consumption reduction and buffer isolation.

Voltage Reference Applications

• Microcontroller or FPGA systems with integrated ADC/DAC
• Data acquisition systems requiring high precision
• Automotive control and monitoring circuits

Voltage Reference Procurement Notes

Verify the specific suffix 'HMSE' indicates the H-grade temperature range (-40°C to 125°C) and MSOP package. Confirm the '#PBF' designation ensures RoHS compliance. Cross-reference the full part number against the manufacturer's latest ordering information to ensure availability and correct pinout configuration for the 16-lead plastic MSOP.

Voltage Reference Selection Notes

Select this component when both high accuracy (±0.05%) and low drift (10ppm/°C) are required across an extended industrial temperature range. The dual-output architecture simplifies designs needing simultaneous precision references and powered supplies. Ensure the application benefits from the combined Refulator™ functionality rather than discrete components.

Voltage Reference Part Context

This part belongs to the LT6658 family of precision dual output references. The 'A' grade denotes the highest accuracy and lowest drift specifications within the series. The 'H' suffix specifies the extended temperature range variant, distinguishing it from the standard I-grade parts limited to 85°C.

Voltage Reference Replacement Considerations

LT6658AIMSE-5#PBF offers identical electrical characteristics but is rated for a lower maximum operating temperature of 85°C instead of 125°C.
