• Buffered output capable of sourcing and sinking current
• Low noise performance minimizes measurement uncertainty
• Wide input voltage range supporting high-voltage applications

Voltage Reference Applications

• Automotive control and monitoring systems
• High-temperature industrial sensing and control
• High-resolution data acquisition systems
• Precision regulators and instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates the mini tape and reel packaging configuration containing 500 pieces. Confirm the H-grade designation corresponds to the -40°C to +125°C operating temperature range. Ensure compatibility with the SOT-23-6 footprint during PCB layout. Check for automotive qualification requirements if deploying in vehicle environments, as standard parts may differ from W-suffix versions.

Voltage Reference Selection Notes

Select this part when a 3V reference with A-grade accuracy (±0.05%) and low drift (10ppm/°C) is required. The H-grade ensures operation at elevated temperatures up to 125°C. Consider the buffered output drive capability if driving moderate loads without external amplification. Verify that the 36V maximum input voltage meets the system power supply constraints.

Voltage Reference Part Context

This component belongs to the LT6654 family of small precision voltage references designed for high accuracy and low noise. The family includes various output voltages and temperature grades, such as I-grade (-40°C to 85°C), H-grade (-40°C to 125°C), and MP-grade (-55°C to 125°C). The LS8 package variant offers hermetic stability, while the S6 package provides a low-profile solution.
