LT6654AHS6-3.3#TRPBF

Voltage Reference Overview

The LT6654AHS6-3.3#TRPBF is a precision series voltage reference from Analog Devices, offering a fixed 3.3V output with ±0.05% initial accuracy and a maximum temperature coefficient of 10ppm/°C. It operates within a supply range of VOUT + 0.5V to 36V, drawing 350µA typical supply current. The device provides buffered ±10mA output drive capability and features low noise (1.7ppm P-P) and thermal hysteresis. Packaged in a 6-lead TSOT-23, it is specified for operation from –40°C to +125°C.

Voltage Reference Feature Summary

• High precision with curvature compensation ensuring low drift and tight initial accuracy
• Buffered output stage capable of sourcing and sinking ±10mA with low output impedance
• Low noise performance minimizes measurement uncertainty in sensitive circuits
• Wide input voltage range supports high-voltage applications up to 36V

Voltage Reference Applications

• Automotive control and monitoring systems
• High-temperature industrial sensing and process control
• High-resolution data acquisition systems requiring stable references
• Precision regulators and instrumentation equipment

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the H-grade designation corresponds to the required –40°C to +125°C operating temperature range for your application environment. Ensure compatibility with the 6-lead TSOT-23 footprint during PCB layout.

Voltage Reference Selection Notes

Select this part for applications requiring high accuracy and low drift in a compact surface-mount package. The A-grade specification ensures tighter tolerance than B-grade options. Consider the LS8 package variant if superior long-term stability and lower hysteresis are critical, noting the difference in physical dimensions and pinout.

Voltage Reference Part Context

This component belongs to the LT6654 family of wide-supply precision voltage references. The family includes various output voltages and grades (I, H, MP) packaged in TSOT-23 or hermetic LS8 formats. The LT6654 is designed for automotive and industrial use, featuring advanced manufacturing techniques for stability across extreme temperatures.

Voltage Reference Replacement Considerations

LT6654BHS6-3.3#TRPBF offers similar functionality with relaxed ±0.1% accuracy and 20ppm/°C drift specifications.
