LT6654BHS6-1.25#TRPBF

Voltage Reference Overview

The LT6654BHS6-1.25#TRPBF is a precision voltage reference from Analog Devices, offering a fixed output of 1.25V with an initial accuracy of ±0.10% and a maximum temperature coefficient of 20ppm/°C. It operates within a supply range up to 36V and supports a specified temperature range of –40°C to 125°C. The device features low noise (1.6ppm P-P from 0.1Hz to 10Hz) and provides buffered output drive capability of ±10mA. Packaged in a 6-lead SOT-23, it ensures stable performance with low dropout voltage and high line regulation.

Voltage Reference Feature Summary

• High accuracy with curvature compensation for minimal drift
• Buffered output capable of sourcing and sinking current
• Low noise performance minimizes measurement uncertainty
• Wide supply voltage range supporting diverse power environments

Voltage Reference Applications

• Automotive control and monitoring systems
• High-temperature industrial sensing applications
• 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 the B-grade designation aligns with the required ±0.10% accuracy and 20ppm/°C drift specifications for your design. Ensure the automotive qualification status matches project requirements, as standard and automotive versions may differ in reliability reporting.

Voltage Reference Selection Notes

Select this component when a compact SOT-23 package is required alongside moderate precision needs. The B-grade offers a balance between cost and performance for general-purpose references. Consider the A-grade if tighter 10ppm/°C drift or 0.05% accuracy is necessary. Verify input voltage constraints relative to the 1.25V output for optimal dropout performance.

Voltage Reference Part Context

This part belongs to the LT6654 family of wide supply, high-output drive precision references. It shares core architecture with other grades like AIS6 and AMPS6 but differs in temperature range and accuracy specifications. The HS6 suffix denotes the H-grade temperature rating suitable for extended industrial environments compared to the standard I-grade.

Voltage Reference Replacement Considerations
