LT6654AMPS6-3.3#TRPBF

Voltage Reference Overview

The LT6654AMPS6-3.3#TRPBF is a precision voltage reference from Analog Devices, featuring a fixed 3.3V output with ±0.05% initial accuracy and a maximum temperature coefficient of 10ppm/°C. It operates within an extended temperature range of –55°C to 125°C and supports input voltages up to 36V. The device provides buffered output drive capability of ±10mA with low output impedance. Key electrical characteristics include a typical supply current of 350µA, line regulation of 5ppm/V, and peak-to-peak noise of 1.7ppm in the 0.1Hz to 10Hz band.

Voltage Reference Feature Summary

• High accuracy with curvature compensation for minimal drift
• Buffered output capable of sourcing and sinking current
• Low thermal hysteresis ensures stability across temperature cycles

Voltage Reference Applications

• Automotive control and monitoring systems
• High resolution data acquisition systems
• Precision regulators and instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the MP grade designation aligns with the required –55°C to 125°C operating range for your application environment. Ensure compatibility with the 6-lead TSOT-23 package dimensions during PCB layout.

Voltage Reference Selection Notes

Select this part for applications requiring wide supply voltage tolerance up to 36V combined with high precision. The MP grade offers the widest industrial temperature range available in the SOT-23 package. Consider the low dropout characteristic if input voltage headroom is limited relative to the 3.3V output.

Voltage Reference Part Context

This component belongs to the LT6654 family of small precision voltage references designed for portable equipment and automotive use. The AMPS6 variant specifically denotes the A-grade performance metrics housed in a miniaturized 6-lead plastic TSOT-23 surface mount package suitable for space-constrained designs.
