LT6658BIDE-3#PBF

Overview

The LT6658BIDE-3#PBF is a precision dual output voltage reference from Analog Devices, featuring a fixed 3V output with an initial accuracy of ±0.1% and a maximum temperature coefficient of 20 ppm/°C. It operates within a specified junction temperature range of -40°C to +85°C and supports a maximum input voltage of 36V. The device provides up to 150mA sourcing current on Output 1 and 50mA on Output 2, utilizing a 16-lead DFN package.

Feature Summary

• Combines precision voltage reference performance with linear regulator capabilities for high-current driving.
• Features Kelvin sense connections to achieve ultra-low load regulation across varying load conditions.
• Includes separate supply pins for each output to allow power consumption reduction and buffer isolation.

Applications

• Driving reference inputs of high-resolution ADCs and DACs under heavy loading
• Powering microcontrollers and other circuitry simultaneously with analog signals
• Precision low noise regulators in data acquisition systems

Procurement Notes

Verify the specific B-grade tolerance and DFN package configuration against the official datasheet before procurement. Confirm that the required operating temperature range aligns with the I-grade specification limits. Ensure proper thermal management practices are implemented due to the exposed pad design requirements.

Selection Notes

Select this component when dual tracking outputs with identical precision specifications are required. Consider the B-grade accuracy if standard precision suffices over A-grade requirements. Evaluate the need for separate supply pins to optimize system power efficiency and signal isolation between channels.

Part Context

This part belongs to the LT6658 family of Refulators, which integrate reference and regulator functions. It is available in MSOP and DFN packages with various voltage options including 1.2V, 1.8V, 2.5V, 3V, 3.3V, and 5V. The family supports both tube and tape-and-reel packaging formats for different manufacturing needs.

Replacement Considerations

LT6658AIMSE-3#PBF offers higher accuracy (±0.05%) and lower drift (10 ppm/°C) in the same DFN package. LT6658BIMSE-3#PBF provides equivalent electrical performance but utilizes an MSOP-16 package instead of DFN.
