LT6654BHS6-2.048#WTRPBF

Voltage Reference Overview

The LT6654BHS6-2.048#WTRPBF is a precision series voltage reference from Analog Devices, offering a fixed output of 2.048V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. It operates within a supply range up to 36V and supports sourcing and sinking currents of ±10mA. The device features low noise (1.6ppm P-P) and low dropout characteristics. Packaged in a 6-lead SOT-23, it is qualified for automotive applications under AEC-Q100 standards and specified for operation between -40°C and +125°C.

Voltage Reference Feature Summary

• AEC-Q100 qualified for automotive reliability requirements
• High output drive capability with buffered output stage
• Low thermal hysteresis and long-term stability
• Wide input voltage range supporting high-voltage systems

Voltage Reference Applications

• Automotive control and monitoring systems
• High-temperature industrial sensing
• High-resolution data acquisition systems
• Precision regulators and instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix #WTRPBF confirms the automotive grade qualification and tape-and-reel packaging format. Ensure the B-grade designation matches the required 20ppm/°C drift specification for your application. Confirm the SOT-23 package dimensions align with your PCB footprint constraints before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when automotive certification is mandatory alongside moderate precision requirements. The B-grade offers a balance of cost and performance compared to the higher-accuracy A-grade. Consider the 20ppm/°C drift if operating across wide temperature swings. Verify that the 10mA drive current meets the load requirements without external buffering.

Voltage Reference Part Context

This part belongs to the LT6654 family of small precision voltage references designed for high accuracy and low noise. The family includes various output voltages and packages, such as the LS8 hermetic option. The BHS6 variant specifically targets the automotive market with extended temperature ranges and robust manufacturing controls defined by AEC-Q100 standards.

Voltage Reference Replacement Considerations

LT6654BIS6-2.048#WTRPBF: Same electrical specs but limited to -40°C to 85°C. LT6654AMPS6-2.048#TRMPBF: Higher accuracy (±0.05%) and wider temp (-55°C to 125°C), but not explicitly marked #W for automotive.
