LT6658BHDE-5#TRPBF

Overview

The LT6658BHDE-5#TRPBF is a precision dual output voltage reference from Analog Devices, featuring a fixed 5V output in a 16-lead DFN package. It combines high accuracy with low noise and high current drive capabilities. The device includes thermal shutdown protection and separate supply pins for each output to reduce power consumption and isolate buffer amplifiers. Both outputs track each other over temperature and load variations.

Feature Summary

• Dual output configuration with identical precision specifications that track each other across temperature and load changes
• High current drive capability supporting up to 150mA sourcing on Output 1 and 50mA sourcing on Output 2
• Kelvin sense connections enable extremely low load regulation performance under heavy loading conditions
• Separate supply pins allow independent power management and isolation of internal buffer amplifiers

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 indicates tape and reel packaging when ordering. Confirm the H-grade designation corresponds to the extended -40°C to +125°C operating junction temperature range required for your application environment. Ensure compatibility with the 16-lead DFN footprint during PCB layout.

Selection Notes

Select this part for applications requiring simultaneous high-current drive and low-noise precision. The B-grade offers 0.1% initial accuracy and 20ppm/°C drift. Consider the DFN package for thermal management needs. Verify input voltage requirements meet the minimum dropout specifications for the 5V output option.
