LT6654AIS6-3#TRMPBF

Voltage Reference Overview

The LT6654AIS6-3#TRMPBF is a precision series voltage reference from Analog Devices, featuring a fixed 3V output. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 6-lead SOT-23 package. Key electrical specifications include an initial accuracy of ±0.05%, a maximum temperature coefficient of 10ppm/°C, and a supply current of 350µA typical. The device supports a maximum input voltage of 36V and provides buffered output drive capability.

Voltage Reference Feature Summary

• Curvature compensation technology ensures high accuracy with low thermal drift
• Buffered output stage enables sourcing and sinking currents for precise load regulation
• Low noise performance minimizes measurement uncertainty in sensitive circuits

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging containing 500 pieces. Confirm the I-grade designation matches the required -40°C to +85°C operating range. Ensure the A-grade accuracy and 10ppm/°C drift specifications align with system requirements before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a stable 3V reference is needed in space-constrained designs requiring SOT-23 packaging. The I-grade specification suits standard industrial environments. Consider the H-grade or MP-grade variants if operation beyond +85°C or below -40°C is required. Verify that the 350µA supply current meets power budget constraints.

Voltage Reference Part Context

This part belongs to the LT6654 family of small precision voltage references designed for wide supply ranges up to 36V. The family includes various output voltages and temperature grades. The AIS6 variant specifically denotes the I-grade temperature range and SOT-23 plastic package form factor.

Voltage Reference Replacement Considerations

LT6654BIS6-3#TRMPBF offers similar functionality with B-grade accuracy (±0.1%) and higher temperature coefficient (20ppm/°C). LT6654AHS6-3#TRMPBF provides the same A-grade electrical performance but extends the operating temperature range to +125°C.
