LT6658AHMSE-2.5#TRPBF

Overview

The LT6658AHMSE-2.5#TRPBF is a precision dual output voltage reference and supply from Analog Devices, operating at a nominal 2.5V output. It combines low drift and low noise performance with linear regulator capabilities. Output 1 provides up to 150mA sourcing current, while Output 2 supports up to 50mA. The device features separate supply pins for each output to reduce power consumption and isolate buffer amplifiers. It includes thermal shutdown protection and is available in a 16-lead MSOP package.

Feature Summary

• Dual outputs track each other over temperature and load with identical precision specifications
• Kelvin sense connections enable high accuracy load regulation under heavy loading conditions
• Separate supply pins allow isolation of buffer amplifiers and optimized power management
• Integrated thermal shutdown protects against thermal overstress during fault conditions

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the AH grade corresponds to the required -40°C to 125°C junction temperature range for your application environment. Ensure the 16-lead MSOP footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when simultaneous high-current buffering and precision referencing are required. The dual-output architecture simplifies designs needing both analog reference and digital supply rails. Consider the separate VIN pins if independent power domain isolation is necessary to minimize cross-talk between sensitive analog and digital sections.

Part Context

This part belongs to the LT6658 family of Refulator devices, which merge voltage reference and linear regulator functions. The AH designation specifies the H-grade temperature range (-40°C to 125°C) and A-grade initial accuracy (±0.05%). The MSE suffix denotes the 16-lead plastic MSOP package with an exposed pad for thermal dissipation.

Replacement Considerations

LT6658AIMSE-2.5#TRPBF offers the same electrical characteristics but operates within the I-grade temperature range (-40°C to 85°C). Verify that the reduced maximum operating temperature meets your system requirements before substituting.
