LT6658BIDE-3#TRPBF

Overview

The LT6658BIDE-3#TRPBF is a precision dual output voltage reference from Analog Devices, housed in a 16-lead DFN package. It provides a fixed 3V output with an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device supports up to 36V input voltage and features separate supply pins for each output. Output 1 delivers up to 150mA sourcing current, while Output 2 provides up to 50mA. It includes thermal shutdown protection and operates within a junction temperature range of -40°C to 85°C.

Feature Summary

• Dual independent outputs with identical precision specifications that track each other over temperature and load variations
• Kelvin sense connections enable high load regulation performance under heavy loading conditions
• Separate supply pins allow for power consumption reduction and buffer amplifier isolation
• Integrated noise reduction pin allows band-limiting and lowering of total integrated noise

Applications

• Microcontroller or FPGA systems requiring dedicated ADC/DAC references
• High-resolution data acquisition systems
• Automotive control and monitoring circuits
• Precision low noise regulator designs

Procurement Notes

Verify the specific B-grade accuracy and 20ppm/°C temperature coefficient requirements against your system design needs. Confirm the DFN-16 package footprint compatibility with your PCB layout. Ensure the 3V fixed output meets your voltage reference specifications before finalizing procurement.

Selection Notes

Select this component when dual isolated references are required from a single IC. The B-grade offers cost-effective precision compared to A-grade options. Consider the separate VIN1/VIN2 pins if independent power domains are necessary for noise isolation in sensitive analog front ends.

Part Context

This part belongs to the LT6658 family of Refulator devices combining voltage reference and linear regulator performance. It is available in MSOP and DFN packages with various voltage options including 1.2V, 1.8V, 2.5V, 3.3V, and 5V. The B-grade variant provides standard precision specifications suitable for general industrial applications.

Replacement Considerations

LT6658BIDE-3#PBF is the tube version of the same electrical specification.
