INA145UA/2K5

Overview

The INA145UA/2K5 is a precision instrumentation amplifier manufactured by Texas Instruments, designed for high-performance signal conditioning applications. It features a fixed gain of 10 V/V and integrates a precision voltage reference to ensure accurate measurements in demanding environments. The device operates within a wide supply voltage range and offers low drift characteristics, making it suitable for industrial process control and medical equipment where stability and accuracy are critical requirements.

Feature Summary

• Integrated precision voltage reference for enhanced measurement accuracy
• Fixed gain configuration simplifies circuit design
• Low drift specifications ensure long-term stability

Applications

• Industrial process control systems requiring precise signal amplification
• Medical instrumentation needing high common-mode rejection
• Data acquisition systems with stringent accuracy demands
• Strain gauge and load cell interfaces

Procurement Notes

Verify the specific suffix /2K5 indicates tape-and-reel packaging when ordering. Confirm that the fixed gain version meets your system requirements without external resistor adjustments. Ensure compatibility with your operating temperature range and supply voltage constraints before finalizing procurement decisions.

Selection Notes

Select this component when a fixed gain of 10 is required alongside integrated reference capabilities. Compare against adjustable gain alternatives if flexibility is needed. Consider power consumption and package size relative to board space constraints. Validate performance against noise and drift specifications for your specific application environment.

Part Context

This part belongs to the INA14x family of instrumentation amplifiers from Texas Instruments. It shares architectural similarities with other members but differs in fixed gain settings and integrated reference features. Understanding the broader family helps in selecting variants with different gains or packaging options for similar applications.

Replacement Considerations

Direct replacements must match the fixed gain of 10 and integrated reference feature. Verify pin compatibility and electrical parameters such as bandwidth and slew rate. Consult manufacturer substitution guides for confirmed equivalents that maintain performance levels in existing designs.
