LT6658AIDE-1.8#TRPBF

Overview

The LT6658AIDE-1.8#TRPBF is a precision dual output voltage reference from Analog Devices, packaged in a 16-lead (4mm × 3mm) plastic DFN with an exposed thermal pad. It provides a fixed 1.8V 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 85°C and accepts input voltages up to 36V.

Feature Summary

• Combines the performance of a precision voltage reference and a linear regulator
• Features two independent outputs that track each other over temperature and load
• Includes Kelvin sense connections for high-precision load regulation
• Provides separate supply pins for each output to reduce power consumption

Applications

• Microcontroller or FPGA with ADC/DAC applications
• Data acquisition systems
• Precision low noise regulators

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the A-grade designation matches the required 0.05% accuracy and 10ppm/°C drift specifications. Ensure the DFN package footprint aligns with the PCB layout requirements for the 4mm × 3mm form factor.

Selection Notes

Select this part for applications requiring dual, tightly tracking voltage rails with high current capability. The A-grade specification ensures superior initial accuracy and lower temperature drift compared to B-grade alternatives. Consider the exposed pad for thermal management if operating near maximum load currents.

Part Context

This component belongs to the LT6658 family of Refulator™ devices, which integrate precision reference and regulator functions. The 'A' grade denotes tighter electrical tolerances, while 'IDE' specifies the DFN package and 1.8V output option. The '#TRPBF' suffix confirms tape-and-reel shipping and lead-free compliance.

Replacement Considerations

LT6658AIMSE-1.8#TRPBF offers identical electrical characteristics but utilizes a 16-lead MSOP package instead of the DFN form factor.
