LT6654BXMS8-2.5#TRPBF

Voltage Reference Overview

The LT6654BXMS8-2.5#TRPBF is a precision voltage reference providing a fixed 2.5V output, rated for operation up to a 175°C junction temperature. It operates from supply voltages up to 36V and is fully specified across the –40°C to 175°C range. The device features a buffered output capable of sourcing 3mA and sinking 10mA at maximum temperature, with low output impedance. Key electrical parameters include an initial accuracy of ±0.1%, a temperature coefficient of 20ppm/°C, and line regulation of 30ppm/V max. It exhibits low thermal hysteresis (30ppm) and low noise (1.5ppm P-P). The component is housed in an 8-lead MSOP package.

Voltage Reference Feature Summary

• Rated for high-temperature operation up to 175°C junction temperature
• Wide supply voltage range supporting inputs up to 36V
• Buffered output provides both sourcing and sinking current capabilities
• Low thermal hysteresis ensures high accuracy over extreme temperature cycles

Voltage Reference Applications

• Oil and gas exploration instrumentation
• Down-hole drilling systems
• Avionics equipment
• Heavy industrial applications
• High-temperature automotive circuits

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube. Confirm the X-grade designation matches the required –40°C to 175°C operating range. Ensure the MSOP-8 package footprint aligns with the PCB layout. Check for AEC-Q100 qualification if automotive reliability standards are mandatory for the application environment.

Voltage Reference Selection Notes

Select this part when high-temperature stability is critical, as it is tested at 175°C. Choose the buffered version for applications requiring load regulation and drive capability. Consider the 36V input range for direct connection to higher voltage rails without pre-regulation. Evaluate power dissipation limits at high ambient temperatures to ensure junction temperature remains within specifications.

Voltage Reference Part Context

This component belongs to the LT6654 family of precision voltage references. Unlike standard versions limited to 125°C or 150°C, the BX grade is specifically engineered for extended thermal environments. It shares architectural similarities with other series references but offers enhanced thermal endurance suitable for harsh operational conditions where standard components would fail.
