LT6658BIMSE-1.8#PBF

Voltage Reference Overview

The LT6658BIMSE-1.8#PBF is a precision dual output voltage reference from Analog Devices, operating at a fixed 1.8V output. It combines the performance of a low drift, low noise reference with that of a linear regulator. The device features B-grade specifications, including an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. It operates within a specified junction temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

• Dual outputs track each other over temperature and load variations
• Kelvin sense connections enable high current sourcing capability
• Separate supply pins allow for power consumption reduction and buffer isolation

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates RoHS compliance when ordering. Confirm the package type matches the design requirements, as this part utilizes the MSOP-16 form factor. Ensure the B-grade performance meets the system's accuracy needs before finalizing procurement.

Voltage Reference Selection Notes

Select this component when dual tracking outputs are required for simultaneous ADC/DAC referencing. The B-grade offers a balance of cost and performance suitable for general precision applications. Consider the H-grade if operation above 85°C is necessary.

Voltage Reference Part Context

This part belongs to the LT6658 family of Refulators, which integrate precision reference and linear regulator functions. The 'BI' designation identifies it as a B-grade device in the MSOP-16 package with a 1.8V output. Other variants include A-grade for higher accuracy and HMSE for extended temperature ranges.

Voltage Reference Replacement Considerations

LT6658AIMSE-1.8#PBF provides higher accuracy (A-grade). LT6658AHMSE-1.8#PBF extends the operating temperature range to 125°C. LT6658BIDE-1.8#PBF offers the same electrical performance in a DFN package.
