Instructions for Using the INA138NA
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.
Input Configuration:
- Connect the input signals to the non-inverting (IN+) and inverting (IN-) inputs.
- The common-mode input range extends from 0V to VCC - 1.5V. Ensure the input signals are within this range to avoid distortion or damage.
Output Configuration:
- The output voltage swing is from 0.1V to VCC - 0.1V. Use appropriate load resistors to ensure the output remains within these limits.
- The output impedance is 100Ω, which should be considered when connecting to subsequent stages.
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 100μV but can range up to 400μV. This should be accounted for in precision applications.
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/μs, which limits the maximum rate of change of the output voltage.
Common-Mode Rejection Ratio (CMRR):
- The CMRR is 90dB, indicating good rejection of common-mode signals. This is crucial for differential signal processing.
Power Supply Rejection Ratio (PSRR):
- The PSRR is 80dB, which helps in reducing the effect of power supply variations on the output.
Operating Temperature:
- The device is rated for operation from -40°C to 125°C. Ensure the ambient temperature does not exceed these limits to maintain reliability.
Handling and Storage:
- Handle the device with care to avoid electrostatic discharge (ESD) damage. Store in a dry, cool place away from direct sunlight.
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.
