Instructions for Using the INA138NA

1. Power Supply:

   • The INA138NA operates over a wide supply voltage range from 2.7V to 36V. Ensure the supply voltage is within this range to avoid damage.

2. Input Configuration:

   • Connect the input signals to the non-inverting (IN+) and inverting (IN-) inputs.
   • The common-mode input range extends from 0V to V_CC - 1.5V. Ensure the input signals are within this range to avoid distortion or damage.

3. Output Configuration:

   • The output voltage swing is from 0.1V to V_CC - 0.1V. Use appropriate load resistors to ensure the output remains within these limits.
   • The output impedance is 100惟, which should be considered when connecting to subsequent stages.

4. Biasing and Offset:

   • The input bias current is very low, typically around 10nA, but can vary from 1nA to 100nA. Use high-value resistors for biasing if necessary.
   • The input offset voltage is typically 100渭V but can range up to 400渭V. This should be accounted for in precision applications.

5. Frequency Response:

   • The bandwidth is 1.2MHz at a gain of 1. For higher gains, the bandwidth will decrease.
   • The slew rate is 0.5V/渭s, which limits the maximum rate of change of the output voltage.

6. Common-Mode Rejection Ratio (CMRR):

   • The CMRR is 90dB, indicating good rejection of common-mode signals. This is crucial for differential signal processing.

7. Power Supply Rejection Ratio (PSRR):

   • The PSRR is 80dB, which helps in reducing the effect of power supply variations on the output.

8. Operating Temperature:

   • The device is rated for operation from -40掳C to 125掳C. Ensure the ambient temperature does not exceed these limits to maintain reliability.

9. Handling and Storage:

   • Handle the device with care to avoid electrostatic discharge (ESD) damage. Store in a dry, cool place away from direct sunlight.

10. Application Notes:

    • Refer to the datasheet and application notes for specific circuit configurations and design considerations. These documents provide detailed information on optimizing performance in various applications.
