Instructions for Using the INA3221AIRGV
Power Supply:
- Connect the supply voltage (VDD) to the appropriate pin, ensuring it is within the range of 2.7V to 5.5V.
- Ensure the ground (GND) is properly connected to the circuit ground.
Input Connections:
- Connect the differential input signals to the IN1P, IN1N, IN2P, IN2N, IN3P, and IN3N pins.
- The common-mode input voltage range should be between 0V and VDD - 0.2V.
- The differential input voltage range should not exceed ±1.2V.
Output Configuration:
- The output voltage (VOUT) will be proportional to the differential input voltage, with a gain of 20 V/V.
- The output voltage range is from 0.01V to VDD - 0.01V.
Temperature Considerations:
- Ensure the device operates within the temperature range of -40°C to 125°C.
Noise and Interference:
- To minimize noise and interference, use proper PCB layout techniques such as short traces, decoupling capacitors, and shielding if necessary.
Common-Mode Rejection:
- The device has a high common-mode rejection ratio (CMRR) of 84 dB, which helps in rejecting common-mode signals.
Power Supply Rejection:
- The power supply rejection ratio (PSRR) is also 84 dB, which helps in maintaining stable performance despite power supply variations.
Bandwidth:
- The bandwidth of the device is 160 kHz, suitable for most low-frequency applications.
Storage and Handling:
- Store the device in a dry environment and handle with care to avoid damage to the sensitive components.
Testing:
- Before finalizing the design, test the device under various conditions to ensure it meets the required specifications and performance criteria.
