Overview
The INA240A1D is a unidirectional current sense amplifier manufactured by Texas Instruments. It features a fixed gain of 20 V/V and supports a common-mode voltage range from -4 V to 80 V. The device operates on a single supply voltage between 2.7 V and 5.5 V, consuming 2.4 mA of supply current. Key electrical specifications include a maximum input offset voltage of 5 µV, an input bias current of 90 µA, and a common-mode rejection ratio of 132 dB. It offers a gain error of 0.05% and accuracy of 0.02%. The component is housed in an SOIC-8 package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Provides high-precision current sensing with ultra-low input offset voltage and minimal gain error for accurate measurements.
- Supports bidirectional operation with a wide common-mode voltage range extending from negative potentials up to 80 V.
- Delivers high common-mode rejection ratio to maintain signal integrity in noisy environments.
Applications
- Industrial motor control systems
- Power supply monitoring circuits
- Battery management systems
Procurement Notes
Verify the specific suffix 'D' indicates the SOIC-8 tube packaging variant distinct from the 'DR' reel version. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the fixed 20 V/V gain meets your system's dynamic range needs without external calibration adjustments.
Selection Notes
Select this component when a fixed 20 V/V gain is required for high-side or low-side current sensing applications. It is suitable for designs needing wide common-mode voltage tolerance up to 80 V. Consider the SOIC-8 package constraints and operating temperature range limits during thermal design.
Part Context
This part belongs to the INA240 family of ultra-precise current sense amplifiers. It shares core electrical characteristics with variants like the INA240A1DR but differs in packaging format. The family is designed for applications requiring high accuracy and robust performance in industrial and automotive environments.
Replacement Considerations
The INA240A1DR is a direct functional substitute with identical electrical specifications, differing only in tape-and-reel packaging instead of tubes.
