LT6658AIMSE-3#TRPBF

Overview

The LT6658AIMSE-3#TRPBF is a precision dual output voltage reference in a 16-lead MSOP package. It provides a nominal 3V 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. Output 1 supports sourcing up to 150mA and sinking up to 20mA, while Output 2 supports sourcing up to 50mA and sinking up to 20mA. Both outputs track each other over temperature and load variations.

Feature Summary

• Combines the performance of a precision voltage reference and a linear regulator for driving high-resolution ADCs and DACs.
• Features separate supply pins for each output to reduce power consumption and isolate buffer amplifiers.
• Includes Kelvin sense connections on outputs to achieve low load regulation under heavy loading conditions.

Applications

• Dual output tracking reference systems
• Microcontroller or FPGA applications with integrated ADC/DAC
• Data acquisition systems
• Precision low noise regulators

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the AIMSE designation corresponds to the A-grade specifications and MSOP package type required for your design. Ensure compatibility with the –40°C to 85°C operating temperature range before finalizing procurement.

Selection Notes

Select this component when dual isolated outputs with identical precision are required. The A-grade offers tighter accuracy and drift specifications compared to B-grade options. Consider the exposed pad thermal management requirements inherent to the MSOP package for high-current sourcing applications.

Part Context

This part belongs to the LT6658 family of Refulator devices from Analog Devices. It is designed to replace traditional discrete reference and regulator combinations, offering a compact solution for space-constrained designs requiring high precision and low noise in data conversion circuits.

FAQ

Can the output voltage be adjusted?

Yes, each output can be configured with external resistors to provide an output voltage up to 6V.

What is the purpose of the OD pin?

The OD pin allows for shutdown control; pulling it low disables the outputs to reduce power consumption.
