LT6654AIS6-5#TRMPBF

Voltage Reference Overview

The LT6654AIS6-5#TRMPBF is a precision series voltage reference from Analog Devices, offering a fixed 5V output with ±0.05% initial accuracy and a maximum temperature coefficient of 10ppm/°C. It operates within an extended industrial temperature range of –40°C to 85°C and supports input voltages up to 36V. The device features low dropout characteristics, low thermal hysteresis, and a buffered output capable of sourcing and sinking ±10mA. Packaged in a compact 6-lead SOT-23 (TSOT-23) format, it ensures stable performance for high-resolution data acquisition systems.

• Buffered output stage enabling ±10mA drive capability with low output impedance
• Low noise performance minimizing measurement uncertainty in sensitive circuits
• Wide supply range operation supporting inputs up to 36V

Voltage Reference Applications

• High resolution data acquisition systems
• Industrial sensing and control applications
• Automotive control and monitoring circuits
• Precision regulators and instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel mini packaging containing 500 pieces. Confirm the 'I' grade designation corresponds to the –40°C to 85°C operating range required for your application environment. Ensure compatibility with the 6-lead TSOT-23 footprint during PCB layout. Check for automotive-specific variants if AEC-Q100 qualification is mandatory for your project.

Voltage Reference Selection Notes

Select this part when a 5V reference is needed with strict accuracy requirements in space-constrained designs. The I-grade variant is suitable for standard industrial environments rather than extreme automotive or military temperatures. Consider the LS8 package if lower long-term drift and hysteresis are critical, as the plastic SOT-23 package exhibits higher thermal stress sensitivity compared to hermetic options.

Voltage Reference Part Context

This component belongs to the LT6654 family of small precision voltage references designed for portable equipment and industrial use. The family includes various output voltages and temperature grades, such as H-grade for –40°C to 125°C and MP-grade for –55°C to 125°C. The AIS6-5 variant specifically targets the 5V output requirement within the industrial temperature window using the standard plastic surface-mount package.

Voltage Reference Replacement Considerations

LT6654BIS6-5#TRMPBF offers similar functionality with ±0.10% accuracy and 20ppm/°C drift. LT6654AHS6-5#TRMPBF provides the same accuracy but extends the operating temperature to 125°C. For hermetic package alternatives, consider LT6654AHLS8-5#PBF.
