LT6658AIDE-3#TRPBF

Overview

The LT6658AIDE-3#TRPBF is a precision dual output voltage reference in a 16-lead DFN package. It provides a fixed 3V output with an initial accuracy 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. The device operates within a specified junction temperature range of –40°C to 85°C.

Feature Summary

• Combines precision voltage reference performance with linear regulator capabilities for high-current driving.
• Features Kelvin sense connections on outputs to achieve extremely low load regulation under heavy loading conditions.
• Includes separate supply pins for each output to allow power consumption reduction and buffer amplifier isolation.

Applications

• Dual output tracking reference systems
• Microcontroller or FPGA applications with integrated ADC/DAC
• Data acquisition systems
• Precision low noise regulators

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the A-grade designation matches the required ±0.05% accuracy and 10ppm/°C drift specifications. Ensure the DFN package variant aligns with the PCB footprint requirements for thermal management.

Selection Notes

Select this component when simultaneous high-current drive and ultra-low noise are required for multiple sensitive analog inputs. The dual-output architecture allows powering microcontrollers while simultaneously referencing high-resolution converters without cross-talk interference.

Part Context

This part belongs to the LT6658 family of Refulator devices, which integrate reference and regulator functions. The 'A' grade denotes tighter accuracy specifications compared to the B grade, and the 'IDE' suffix identifies the specific 16-lead plastic DFN package configuration.

Replacement Considerations

LT6658BIDE-3#TRPBF offers similar functionality with relaxed accuracy specifications (±0.1%, 20ppm/°C). LT6658AIMSE-3 variants provide identical electrical performance but utilize a 16-lead MSOP package instead of the DFN form factor.
