LT6658AIMSE-2.5#TRPBF

Overview

The LT6658AIMSE-2.5#TRPBF is a precision dual output voltage reference from Analog Devices, featuring a fixed 2.5V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. It operates within a specified junction temperature range of –40°C to 85°C and utilizes a 16-lead MSOP package. The device integrates Refulator technology, combining low drift and low noise performance with linear regulator capabilities. Output 1 supports up to 150mA sourcing current, while Output 2 supports up to 50mA sourcing current. Both outputs track each other over temperature and load variations.

Feature Summary

• Combines precision voltage reference and linear regulator performance for driving high-resolution ADCs and DACs under heavy loading
• Features Kelvin sense connections on both outputs to achieve ultra-low load regulation
• Provides separate supply pins for each output to allow power consumption reduction and buffer amplifier isolation
• Includes thermal shutdown protection and short circuit protection to prevent thermal overstress

Applications

• Dual output tracking reference systems
• Microcontroller or FPGA applications with integrated ADC/DAC
• Precision data acquisition systems
• Automotive control and monitoring circuits
• Instrumentation and process control equipment

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 temperature coefficient specifications. Ensure the MSOP-16 package form factor aligns with the target PCB layout constraints. Check for any RoHS compliance requirements if applicable to the manufacturing environment.

Selection Notes

Select this component when simultaneous high-current buffering and precision referencing are required for multiple channels. The A-grade specification ensures tighter tolerance bounds compared to B-grade alternatives. Consider the separate VIN1 and VIN2 pins if independent power domains are needed to minimize cross-talk between the two output buffers during operation.

Part Context

This part belongs to the LT6658 family of precision dual output references available in various fixed voltage options including 1.2V, 1.8V, 3V, 3.3V, and 5V. The family is offered in both 16-lead MSOP and 4mm × 3mm DFN packages. Different temperature grades (I-Grade and H-Grade) are available to support varying operational environmental requirements across industrial and automotive sectors.
