LT6658AIDE-3#PBF

Overview

The LT6658AIDE-3#PBF is a precision dual output voltage reference in a 16-lead DFN package. It provides a fixed 3V output with an initial accuracy of ±0.05% and a temperature coefficient of 10 ppm/°C. The device operates within a junction temperature range of -40°C to +85°C and supports a maximum input voltage of 36V. Output 1 delivers up to 150mA sourcing current, while Output 2 provides up to 50mA. Both outputs feature Kelvin sense connections for high load regulation.

Feature Summary

• Dual independent outputs with identical precision specifications that track each other over temperature and load variations.
• Integrated Refulator architecture combining a precision reference with linear regulator capabilities for heavy loading applications.
• Kelvin sense connections on both outputs to achieve ultra-low load regulation under varying current conditions.
• Separate supply pins (VIN1, VIN2) allow for power consumption reduction and buffer amplifier isolation.

Applications

• Microcontroller or FPGA systems requiring integrated ADC/DAC references
• High-resolution data acquisition systems
• Precision instrumentation and process control equipment

Procurement Notes

Verify the specific suffix #PBF indicates RoHS compliance when ordering. Confirm the DE package designation matches the required 16-lead DFN footprint. Ensure the A-grade specification aligns with the required 10 ppm/°C drift performance for the target application environment.

Selection Notes

Select this part for applications requiring simultaneous high-current drive and low-noise precision. The A-grade offers tighter accuracy than B-grade options. Consider the DFN package for thermal management needs compared to MSOP variants. Verify input voltage requirements do not exceed the 36V absolute maximum rating.

Part Context

This component belongs to the LT6658 family of precision dual output references. It shares architectural similarities with other members like the LT6658BIDE-3#PBF but differs in grade specifications. The family utilizes Analog Devices' Refulator technology to merge reference and regulator functions into a single compact solution.
