LT6658BHDE-1.8#TRPBF

Overview

The LT6658BHDE-1.8#TRPBF is a precision dual output voltage reference from Analog Devices, packaged in a 16-lead DFN with an exposed pad and supplied in tape and reel format. It provides two independent outputs configured for 1.8V operation within the H-grade temperature range of -40°C to +125°C. The device features B-grade accuracy with a maximum initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. It supports up to 36V input voltage and includes separate supply pins for each output.

Feature Summary

• Dual output architecture with identical precision specifications that track each other over temperature and load variations
• Kelvin sense connections enable high current sourcing capabilities while maintaining low load regulation
• Separate supply pins allow for power consumption reduction and buffer amplifier isolation
• Integrated thermal shutdown and short circuit protection mechanisms

Applications

• Microcontroller or FPGA systems requiring integrated ADC/DAC references
• Data acquisition systems demanding stable voltage sources
• Automotive control and monitoring circuits
• Precision instrumentation and process control equipment

Procurement Notes

Verify the specific suffix #TRPBF confirms the tape and reel packaging configuration required for automated assembly processes. Ensure the BHDE designation matches the required 1.8V fixed output, B-grade performance metrics, and extended H-grade temperature range. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when dual tracking references are needed for high-resolution data converters. The H-grade rating ensures functionality across the full industrial temperature spectrum. Verify that the 1.8V output aligns with downstream logic levels. Consider the DFN package dimensions for PCB layout constraints and thermal management requirements during the design phase.
