Details
Operating on a single 2.7V to 5.5V power supply, the INA240A3D consumes a maximum of 2.4mA of supply current. It offers four fixed gain options - 20 V/V, 50 V/V, 100 V/V, and 200 V/V - to suit different measurement requirements. Thanks to its zero-drift architecture, the device enables precise current sensing with low drops across the shunt, down to as low as 10mV full-scale. Additionally, the INA240A3D is available in both 8-pin TSSOP and 8-pin SOIC packages, ensuring convenient integration into various designs

FAQs
What is INA240A3D?
The INA240A3D is a high-precision, bidirectional current-sensing amplifier designed by Texas Instruments. It is suitable for applications requiring accurate current measurements in both directions, such as battery management, motor control, and power management systems.
How Does INA240A3D Work?
The INA240A3D operates by monitoring the voltage across a shunt resistor to accurately measure the current passing through it. It amplifies the small voltage drop across the shunt resistor with high precision and low offset, providing a reliable representation of the current flow. The amplifier features a wide input common-mode range and excellent common-mode rejection, ensuring accurate measurements in noisy environments.
How Many Pins does INA240A3D have and What are the Functions of the Pinout Configuration?
The INA240A3D is housed in an SOT-23 package. The pinout configuration includes:
- V+: Positive power supply pin.
- V-: Negative power supply pin.
- VS+: Positive voltage connection for the shunt resistor.
- VS-: Negative voltage connection for the shunt resistor.
- OUT: Amplified output voltage.
- REF: Reference voltage pin.
- SENSEP: Positive current-sense input.
- SENSEN: Negative current-sense input.
What are the Pros and Cons of INA240A3D?
