LT6654AIS6-2.5#TRPBF

Voltage Reference Overview

The LT6654AIS6-2.5#TRPBF 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 an input voltage range of 3V to 36V and draws a supply current of up to 600µA. The device provides buffered output drive capability of ±10mA with low output impedance. Packaged in a 6-lead TSOT-23, it is specified for industrial temperatures ranging from –40°C to 85°C.

Voltage Reference Feature Summary

• Curvature compensation technology ensures high accuracy and low drift across the operating temperature range.
• Buffered output stage delivers ±10mA drive current while maintaining precise load regulation.
• Low noise performance minimizes measurement uncertainty in sensitive signal chains.
• Capable of sinking and sourcing current, allowing operation as a negative voltage reference.

Voltage Reference Applications

• High resolution data acquisition systems
• Industrial sensing and control circuits
• Precision regulators
• Medical equipment

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the A-grade designation matches the required ±0.05% accuracy and 10ppm/°C drift specifications. Ensure the TSOT-23-6 package footprint aligns with the PCB layout. Check that the –40°C to 85°C temperature range meets the application environmental requirements.

Voltage Reference Selection Notes

Select this component for applications requiring high precision in a small surface-mount package. The wide 36V input range accommodates various supply rails. Consider the 600µA supply current for power-sensitive designs. Verify that the ±10mA output drive is sufficient for the intended load without external buffering.

Voltage Reference Part Context

This part belongs to the LT6654 family of small precision voltage references. The family includes variants with different output voltages, accuracy grades (A and B), and temperature ranges (I, H, MP). The AIS6 variant specifically denotes the A-grade accuracy, industrial temperature range, and SOT-23-6 package.

Voltage Reference Replacement Considerations

LT6654AIS6-2.5#TRMPBF offers identical electrical characteristics but in mini-tape and reel packaging.
