LT6654BHS6-2.048#TRMPBF

Voltage Reference Overview

The LT6654BHS6-2.048#TRMPBF 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 a wide operating temperature range from -40°C to +125°C. The device provides buffered output drive capability of ±10mA with low output impedance. Packaged in a 6-lead SOT-23 (TSOT-23) format, it features low noise performance of 1.6ppm P-P (0.1Hz to 10Hz) and low thermal hysteresis.

Voltage Reference Feature Summary

• High accuracy with curvature compensation for low drift
• Buffered output capable of sourcing and sinking current
• Low noise design minimizing measurement uncertainty
• Wide supply voltage operation up to 36V

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 #TRMPBF indicates tape and reel packaging with a quantity of 500 units. Confirm the H-grade designation corresponds to the specified -40°C to 125°C operating range. Ensure compatibility with the 6-lead TSOT-23 footprint during PCB layout. Check for automotive qualification requirements if applicable, as standard parts may differ from W-suffix versions.

Voltage Reference Selection Notes

Select this part when a 2.048V reference with B-grade accuracy (±0.1%) is required. Choose over A-grade variants if cost sensitivity allows for higher drift (20ppm/°C vs 10ppm/°C). Consider the LS8 package if superior long-term stability and lower hysteresis are critical. Verify input voltage constraints relative to the dropout voltage under load conditions.

Voltage Reference Part Context

This component belongs to the LT6654 family of small precision voltage references designed for high accuracy and low power consumption. The family includes various output voltages and packages, such as the hermetic LS8. The B-grade designation signifies a 20ppm/°C temperature coefficient, distinguishing it from the higher precision A-grade options within the same product line.

Voltage Reference Replacement Considerations

LT6654BIS6-2.048#TRMPBF offers identical electrical specifications but is rated for an industrial temperature range of -40°C to 85°C instead of the extended -40°C to 125°C range.
