LT6658AHDE-5#PBF

Voltage Reference Overview

The LT6658AHDE-5#PBF is a precision dual output voltage reference from Analog Devices, housed in a 16-lead (4mm × 3mm) plastic DFN package with an exposed thermal pad. It provides a fixed 5V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device operates within a specified junction temperature range of -40°C to +125°C and supports input voltages up to 36V. Output 1 delivers up to 150mA sourcing current, while Output 2 provides up to 50mA.

Voltage Reference Feature Summary

• Combines precision voltage reference performance with linear regulator capabilities for high-current driving.
• Features two independent outputs that track each other over temperature and load variations.
• Includes Kelvin sense connections on outputs to minimize load regulation errors.
• Offers separate supply pins for each output to allow power consumption reduction and buffer isolation.

Voltage Reference 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

Voltage Reference Procurement Notes

Verify the specific suffix 'AHDE' corresponds to the H-grade (-40°C to 125°C), DFN-16 package, and 5V fixed output configuration. Confirm RoHS compliance via the '#PBF' designation. Ensure the ordering part number matches the exact grade and package required for your thermal and environmental specifications before procurement.

Voltage Reference Selection Notes

Select this component when high current drive capability is required alongside tight tracking between two reference rails. The H-grade ensures operation in extended industrial temperatures. Consider the DFN package for thermal management needs and space-constrained layouts compared to MSOP alternatives.

Voltage Reference Part Context

This part belongs to the LT6658 family of Refulators™, which integrate a precision bandgap reference with low-noise buffer amplifiers. The AHDE variant specifically denotes the higher temperature grade (H) and the DFN-16 package form factor, distinguishing it from the I-grade or MSOP versions within the same product line.

Voltage Reference Replacement Considerations

LT6658BIDE-5#PBF offers similar functionality with lower accuracy (±0.1%) and higher drift (20ppm/°C). LT6658AIMSE-5#PBF provides equivalent electrical performance but uses an MSOP-16 package instead of DFN-16.
