LT6658BIMSE-1.8#TRPBF

Overview

The LT6658BIMSE-1.8#TRPBF is a precision dual output voltage reference from Analog Devices, operating at a fixed 1.8V output with B-grade specifications. It features ±0.1% initial accuracy and a maximum temperature coefficient of 20ppm/°C. The device supports up to 36V input voltage and provides Output 1 sourcing capability of 150mA and Output 2 sourcing capability of 50mA. It utilizes Kelvin sense connections for high load regulation and includes separate supply pins for each output.

Feature Summary

• Dual output architecture with identical precision specifications that track each other over temperature and load variations
• Kelvin sense connection on outputs enabling high current drive capabilities while maintaining low load regulation
• Separate supply pins provided for each output to allow power consumption reduction and buffer amplifier isolation

Applications

• Driving reference inputs of high resolution ADCs and DACs under heavy loading conditions
• Simultaneously powering microcontrollers and other circuitry alongside precision analog components
• Microcontroller or FPGA applications requiring integrated ADC/DAC references
• Precision low noise regulators in instrumentation and process control systems

Procurement Notes

Verify the specific B-grade performance parameters against the official datasheet before integration. Confirm the MSOP-16 package requirements and exposed pad soldering guidelines are met during PCB layout. Ensure input voltage ranges comply with absolute maximum ratings to prevent device damage.

Selection Notes

Select this component when dual tracking references with high current drive are required. The B-grade offers standard precision suitable for general high-resolution data acquisition. Consider A-grade variants if tighter accuracy and lower drift specifications are necessary for the application.
