FAQs

What is INA240A2D?

The INA240A2D is a precision, bidirectional, low- or high-side voltage output current shunt monitor designed by Texas Instruments. It is ideal for applications requiring accurate current measurements, such as motor control, battery management, and power management systems.

How Does INA240A2D Work?

The INA240A2D works by sensing the voltage across an external current-sensing resistor and converting it into a proportional output voltage. It includes a precision amplifier with integrated precision shunt resistor for accurate current measurements. The device features a wide common-mode voltage range and low offset voltage, making it suitable for high-side or low-side current sensing applications.

How Many Pins does INA240A2D have and What are the Functions of the Pinout Configuration?

The INA240A2D is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • V+: Positive power supply pin.
  • V-: Negative power supply pin.
  • VS+: High-side sense voltage input pin.
  • VS-: Low-side sense voltage input pin.
  • OUT: Output pin for the monitored voltage with respect to the REF pin.
  • REF: Reference voltage pin.
  • SET: External gain setting and filtering pin.
  • GND: Ground pin.

What are the Pros and Cons of INA240A2D?

Pros:

  • Precision Monitoring: Provides precise current measurement for accurate system monitoring.
  • Wide Common-Mode Range: Suitable for both high-side and low-side current sensing applications.
  • Integrated Shunt Resistor: Eliminates the need for an external shunt resistor, saving board space and simplifying design.
  • Low Offset Voltage: Ensures accurate measurement with minimal error.
  • Flexible Gain Setting: Allows for tailored output voltage scaling based on the application requirements.

Cons:

  • External Components: May require additional passive components for specific filtering or gain configuration.
  • Operating Temperature Range: The operating temperature range may not be suitable for extreme temperature environments without additional thermal management.

Are There Any Equivalents/Alternatives to INA240A2D for Recommendation?

  • The INA219 from Texas Instruments is an alternative current shunt monitor with similar features and performance.
  • Similar alternatives to the INA240A2D include the MAX4080 from Maxim Integrated and the ACS712 from Allegro MicroSystems.
