LT6654AIS6-1.25#TRMPBF

Voltage Reference Overview

The LT6654AIS6-1.25#TRMPBF is a precision voltage reference from Analog Devices, offering a fixed output of 1.25V with an initial accuracy of ±0.05% and a temperature coefficient of 10ppm/°C. It operates within a supply range of 2.4V to 36V and supports ±10mA output drive current. The device features low noise (1.6ppm P-P) and low dropout characteristics, housed in a 6-lead TSOT-23 package. It is specified for industrial temperatures ranging from -40°C to +85°C.

Voltage Reference Feature Summary

• High accuracy with curvature compensation providing 10ppm/°C drift and ±0.05% initial tolerance
• Buffered output capable of sourcing and sinking ±10mA with low output impedance
• Low noise performance minimizing measurement uncertainty in sensitive circuits
• Wide input voltage capability up to 36V with low thermal hysteresis

Voltage Reference Applications

• Portable equipment requiring stable power supplies
• Industrial sensing and control systems
• Automotive applications meeting AEC-Q100 standards
• High resolution data acquisition systems

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates mini tape and reel packaging containing 500 pieces. Confirm the I-grade designation corresponds to the -40°C to +85°C operating range. Ensure compatibility with surface mount assembly processes for the TSOT-23 package. Check for automotive grade variants if AEC-Q100 qualification is required for the target application.

Voltage Reference Selection Notes

Select this part when a compact solution is needed for high-precision analog circuits. The 1.25V output is suitable for driving ADCs or DACs directly. Consider the 10ppm/°C drift specification against environmental temperature variations. Evaluate the ±10mA drive capability against load requirements to ensure stable regulation under varying conditions.

Voltage Reference Part Context

This component belongs to the LT6654 family of small precision voltage references. The family includes various output voltages and temperature grades, such as H-grade (-40°C to 125°C) and MP-grade (-55°C to 125°C). The AIS6 variant specifically denotes the I-grade temperature range in the SOT-23 package format.
