LT6658BHDE-3#PBF

Overview

The LT6658BHDE-3#PBF is a precision dual output voltage reference from Analog Devices, housed in a 16-lead (4mm × 3mm) plastic DFN package. It provides a fixed 3V output with an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. Designed for the H-grade, it operates within a junction temperature range of –40°C to +125°C. The device supports up to 36V input voltage and features separate supply pins for each output.

Feature Summary

• Combines precision voltage reference performance with linear regulator capabilities
• Dual outputs track each other over temperature and load variations
• Kelvin sense connections enable high current sourcing with low load regulation
• Includes thermal shutdown protection and short circuit prevention

Applications

• Microcontroller or FPGA systems with integrated ADC/DAC
• Data acquisition systems requiring stable references
• Automotive control and monitoring circuits
• Precision low noise regulators

Procurement Notes

Verify the specific suffix DE indicates the DFN package and BH denotes the B-grade specification with H-grade temperature range. Confirm RoHS compliance via the PBF suffix. Check official distributor availability as stock levels fluctuate. Ensure the ordering part number matches the required output voltage and package type exactly before purchase.

Selection Notes

Select this component when dual isolated outputs are needed for driving sensitive analog inputs while powering digital logic. The B-grade offers a balance of cost and performance with 20ppm/°C drift. Consider the DFN package for thermal management requirements. Verify input voltage headroom meets the dropout specifications for the desired load currents.

Part Context

This part belongs to the LT6658 family of Refulator devices. It shares architectural similarities with MSOP variants like the LT6658BHMSE-3#PBF but utilizes a different footprint. The family allows configurable output voltages up to 6V using external resistors, though this specific model provides a fixed 3V setting.
