LT6658AIDE-5#PBF

Overview

The LT6658AIDE-5#PBF is a precision dual output voltage reference from Analog Devices, housed in a 16-lead DFN package. It provides a fixed 5V output with an initial accuracy of ±0.05% and a temperature coefficient of 10 ppm/°C. The device operates within a junction temperature range of -40°C to +85°C and supports a maximum input voltage of 36V. Output 1 delivers up to 150mA sourcing current, while Output 2 provides up to 50mA. Both outputs feature Kelvin sense connections for high load regulation.

Feature Summary

• Combines precision voltage reference performance with linear regulator capabilities for simultaneous high-current driving
• Features separate supply pins for each output to allow power consumption reduction and buffer amplifier isolation
• Includes thermal shutdown protection and short-circuit prevention mechanisms to ensure operational safety

Applications

• Microcontroller or FPGA systems requiring integrated ADC/DAC references
• Data acquisition systems demanding low noise and high stability
• Automotive control and monitoring circuits
• Precision instrumentation and process control equipment

Procurement Notes

Verify the specific suffix #PBF indicates RoHS and WEEE compliance when ordering. Confirm the DFN package type matches your PCB footprint requirements. Ensure the I-grade specification meets your system's accuracy needs. Check for availability constraints as distribution may vary by region.

Selection Notes

Select this part for applications requiring two independent, tracked voltage rails from a single component. The A-grade offers tighter accuracy than B-grade options. Consider the MSOP package if lead space is limited, or the DFN for better thermal management. Verify input voltage headroom requirements against the dropout characteristics.

Part Context

This component belongs to the LT6658 family of Refulator™ devices. Other variants include different output voltages (1.2V, 1.8V, 2.5V, 3V, 3.3V) and grades (A, B, H). Package options include 16-lead MSOP and 4mm × 3mm DFN. The family shares core architecture but varies in thermal range and precision specifications.

Replacement Considerations

LT6658BIDE-5#PBF: Lower accuracy grade (±0.1%, 20 ppm/°C). LT6658AHDE-5#PBF: Extended temperature range (-40°C to 125°C).
