LT6654AMPS6-3.3#TRMPBF

Voltage Reference Overview

The LT6654AMPS6-3.3#TRMPBF is a precision series voltage reference from Analog Devices, offering a fixed 3.3V output with ±0.05% initial accuracy and a maximum temperature coefficient of 10ppm/°C. It operates within an extended temperature range of –55°C to 125°C and supports input voltages up to 36V. The device provides buffered output drive capability of ±10mA with low output impedance. Key electrical characteristics include a typical supply current of 350µA, peak-to-peak noise of 1.7ppm (0.1Hz to 10Hz), and line regulation of 5ppm/V. It is housed in a compact 6-lead TSOT-23 package.

Voltage Reference Feature Summary

• High precision with curvature compensation for low drift and high accuracy
• Buffered output capable of sourcing and sinking ±10mA
• Low noise performance minimizing measurement uncertainty
• Wide operating supply voltage range up to 36V

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 tape and reel packaging containing 500 pieces. Confirm the MP grade designation corresponds to the –55°C to 125°C operating range. Ensure compatibility with the 6-lead TSOT-23 footprint during PCB layout. Check for automotive qualification requirements if applicable, as standard parts may differ from AEC-Q100 qualified versions.

Voltage Reference Selection Notes

Select this part for applications requiring high accuracy and wide supply voltage tolerance in a small form factor. The MP grade ensures operation in extreme cold environments down to –55°C. Consider the ±10mA drive capability for direct interfacing with ADCs or sensors without additional buffering. Verify that the 10ppm/°C drift meets system stability requirements over the full temperature range.

Voltage Reference Part Context

This component belongs to the LT6654 family of precision voltage references designed for high-performance analog circuits. The family includes various output voltages and grades (I, H, MP) packaged in TSOT-23 or LS8 formats. The AMPS6 variant specifically denotes the MP temperature grade with a 3.3V output in the mini TSOT-23 package, optimized for space-constrained designs.

Voltage Reference Replacement Considerations

LT6654BMPS6-3.3#TRMPBF offers similar specifications with B-grade accuracy (±0.1%) and temperature coefficient (20ppm/°C). LT6654AHS6-3.3#TRMPBF provides A-grade performance but is limited to the H-grade temperature range of –40°C to 125°C.
