LT6658AIDE-5#TRPBF

Overview

The LT6658AIDE-5#TRPBF is a precision dual output voltage reference in a 16-lead DFN package. It provides two independent outputs with an initial accuracy of ±0.05% and a temperature coefficient of 10ppm/°C. Output 1 supports up to 150mA sourcing current, while Output 2 supports up to 50mA. The device operates with input voltages up to 36V and features low noise performance of 1.5ppm peak-to-peak from 0.1Hz to 10Hz.

Feature Summary

• Combines precision voltage reference and linear regulator functions for high-resolution ADC and DAC driving
• Features Kelvin sense connections for precise load regulation under heavy loading conditions
• Includes separate supply pins for each output to allow power consumption reduction and buffer isolation

Applications

• Microcontroller or FPGA systems with integrated ADC/DAC
• Data acquisition systems requiring stable reference supplies
• Automotive control and monitoring circuits
• Precision low noise regulator applications

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 DE package variant aligns with the PCB footprint requirements for the 4mm x 3mm DFN form factor.

Selection Notes

Select this component when dual tracking references are needed for mixed-signal designs. The A-grade offers tighter accuracy than B-grade options. Consider the thermal management capabilities of the exposed pad DFN package for high-current applications involving the 150mA output capability.

Part Context

This part belongs to the LT6658 family of Refulator devices. It is available in MSOP and DFN packages with various fixed voltage options including 1.2V, 1.8V, 2.5V, 3V, 3.3V, and 5V. The family integrates high-performance buffering directly onto the die to maintain stability under capacitive loads.
