LT6654AMPS6-2.5#TRMPBF

Voltage Reference Overview

The LT6654AMPS6-2.5#TRMPBF is a precision series voltage reference from Analog Devices, offering a fixed 2.5V output with ±0.05% initial accuracy and a maximum temperature coefficient of 10ppm/°C. It operates within a wide supply range up to 36V and supports an output drive current of ±10mA. The device is fully specified for temperatures ranging from –55°C to +125°C and utilizes a 6-lead TSOT-23 package.

Voltage Reference Feature Summary

• High accuracy with curvature compensation providing low drift and minimal thermal hysteresis
• Buffered output stage capable of sourcing and sinking ±10mA with low output impedance
• Low noise performance minimizing measurement uncertainty in sensitive applications
• Wide input voltage capability allowing operation with minimal dropout voltage

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates mini tape and reel packaging containing 500 pieces. Confirm the MP grade designation ensures the extended –55°C to +125°C operating range required for your application environment. Check for automotive-specific variants if AEC-Q100 qualification is mandatory.

Voltage Reference Selection Notes

Select this part when high precision and wide temperature stability are critical. The MP grade offers the broadest thermal range compared to I or H grades. Ensure the 2.5V output matches system requirements, as other voltages like 1.25V or 5V are available in the same family with identical package and grade options.

Voltage Reference Part Context

This component belongs to the LT6654 family of small precision voltage references. It shares core architectural features with variants such as LT6654AIS6-2.5 and LT6654BHS6-2.5, differing primarily in temperature grade (MP vs I/H) and initial accuracy specifications (A vs B grade).

Voltage Reference Replacement Considerations

LT6654BMPS6-2.5#TRMPBF offers similar functionality with ±0.1% accuracy and 20ppm/°C drift. LT6654AHLS8-2.5#PBF provides hermetic LS8 packaging for superior long-term stability but differs in physical footprint.

Voltage Reference FAQ

Can the LT6654 operate as a negative voltage reference?

Yes, by connecting the output to ground and biasing the internal circuitry with a positive voltage at the VIN pin through a current-limiting resistor.

What is the minimum input voltage required for stable operation?

The datasheet specifies a minimum dropout voltage, requiring VIN to be at least VOUT plus the dropout voltage (typically 55mV to 100mV depending on load) for regulation.
