LT6654AHS6-4.096#TRPBF

Voltage Reference Overview

The LT6654AHS6-4.096#TRPBF is a precision series voltage reference with a fixed output of 4.096V and ±0.05% initial accuracy. It operates within an input voltage range of VOUT + 0.5V to 36V, drawing a maximum supply current of 600µA. The device provides buffered output drive capable of sourcing and sinking ±10mA with low output impedance. It features a temperature coefficient of 10ppm/°C and peak-to-peak noise of 2.0ppm in the 0.1Hz to 10Hz band. Packaged in a 6-lead TSOT-23, it is fully specified for operation from –40°C to 125°C.

Voltage Reference Feature Summary

• High accuracy with curvature compensation providing 10ppm/°C drift and 0.05% initial tolerance
• Buffered output stage enables ±10mA source and sink currents with low output impedance
• Low thermal hysteresis ensures stable performance across wide temperature variations
• Capable of negative voltage reference operation while maintaining positive reference precision

Voltage Reference Applications

• Automotive control and monitoring systems
• High resolution data acquisition systems
• Precision regulators
• Medical equipment
• Instrumentation and process control

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than mini-reel or bulk formats. Confirm the H-grade designation corresponds to the required –40°C to 125°C operating range for your application environment. Ensure compatibility with standard surface mount reflow profiles for the TSOT-23 package.

Voltage Reference Selection Notes

Select this part when high accuracy and low noise are critical in space-constrained designs. The buffered output eliminates the need for external op-amps to drive moderate loads. Consider the LS8 package variant if superior long-term stability and lower hysteresis are required over the plastic TSOT-23 version.

Voltage Reference Part Context

This component belongs to the LT6654 family of small precision voltage references designed for high accuracy and low power consumption. The family includes various output voltages and temperature grades, such as I-grade (–40°C to 85°C) and MP-grade (–55°C to 125°C), offering flexibility for different industrial and automotive environments.

Voltage Reference FAQ

Can the LT6654AHS6-4.096 operate as a negative voltage reference?

Yes, by connecting the output to a negative rail and biasing the internal circuitry with a positive voltage at the VIN pin, it functions as a negative reference with the same precision.

What is the minimum input voltage required for stable operation?

The minimum input voltage is VOUT + 0.5V, ensuring the dropout voltage remains within specified limits for proper regulation.
