LT6658AHMSE-5#TRPBF

Overview

The LT6658AHMSE-5#TRPBF 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 with an exposed pad. The device provides high accuracy with an initial tolerance of ±0.05% and a maximum temperature coefficient of 10ppm/°C. Output 1 supports up to 150mA sourcing current, while Output 2 supports up to 50mA. It accepts input voltages up to 36V and includes thermal shutdown protection.

Feature Summary

• Combines low drift precision reference performance with linear regulator capabilities for heavy load driving
• Features Kelvin sense connections on outputs to achieve ultra-low load regulation
• Includes separate supply pins for each output to allow power consumption reduction and buffer isolation

Applications

• Microcontroller or FPGA systems with integrated ADC/DAC peripherals
• High-resolution data acquisition systems requiring stable reference inputs
• Automotive control and monitoring circuits demanding wide temperature stability
• Precision instrumentation and process control equipment

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the AH designation corresponds to the H-grade temperature range (-40°C to +125°C) and A-grade electrical specifications (±0.05% accuracy, 10ppm/°C). Ensure the MSE package type matches the PCB footprint requirements for the 16-lead MSOP form factor.

Selection Notes

Select this part for applications requiring simultaneous high-current drive and precision referencing. The dual-output architecture allows one channel to power supporting circuitry while the other drives sensitive ADC/DAC references. Consider the separate VIN1/VIN2 pins if independent power domain isolation is required to minimize noise coupling between buffers.

Part Context

This component belongs to the LT6658 family of Refulator™ devices, which merge voltage reference and LDO functions. The AHMSE-5 variant specifically denotes the 5V fixed output option in the H-grade temperature range housed in the MSOP-16 package. It shares architectural similarities with DFN variants but offers distinct thermal and pinout characteristics suitable for surface mount assembly.

Replacement Considerations

LT6658AIMSE-5#TRPBF: Identical electrical performance but limited to I-grade temperature range (-40°C to 85°C).
