Instructions for Use:
Power Supply: The INA111BP can operate with a supply voltage ranging from ±2.25V to ±18V. Ensure the power supply is within these limits to avoid damage.
Input Signals:
- The input voltage range should not exceed VS+0.3V or be less than -0.3V relative to ground.
- For differential input voltage, ensure it remains within the supply rails to prevent potential damage or erratic behavior.
Common-Mode and Power Supply Rejection:
- The device offers high common-mode rejection ratio (CMRR) of 98dB at 1kHz, which helps in rejecting unwanted common-mode signals.
- It also provides a power supply rejection ratio (PSRR) of 90dB at 1kHz, reducing the effect of supply voltage variations on the output.
Bias and Offset Management:
- Input bias current is typically 40nA, and input offset current is around 5nA. These parameters are important for maintaining accurate measurements.
- The input offset voltage can vary between -50μV to +50μV, which should be considered when designing circuits for precision applications.
Output Considerations:
- The output voltage swing is up to ±13.5V with no load when powered by ±15V supplies.
- Ensure that the output signal does not exceed the operational limits to maintain linearity and accuracy.
Frequency Response:
- The bandwidth for small signal operation is 1.2MHz, and the slew rate is 0.7V/μs, which defines the maximum rate of change of the output voltage.
Handling and Storage:
- Handle the device with care to avoid electrostatic discharge (ESD) damage.
- Store in recommended conditions as per the datasheet guidelines to preserve performance characteristics.
For more detailed specifications and application notes, refer to the official datasheet provided by the manufacturer.
