The maximum power dissipation of the INA103KU is 670mW at 25°C. However, it's recommended to derate the power dissipation to ensure reliable operation.
The INA103KU has a common-mode voltage range of ±200mV. Ensure that the input voltage is within this range to maintain accurate operation. You can use voltage dividers or level-shifters to adjust the input voltage if necessary.
To minimize noise and ensure accurate operation, place the INA103KU close to the signal source, and use a ground plane to reduce noise coupling. Keep the input traces short and away from high-current or high-voltage traces.
The gain error of the INA103KU can be calculated using the formula: Gain Error (%) = (Vout - (Vcm + (Vin * G))) / (Vin * G) * 100, where Vout is the output voltage, Vcm is the common-mode voltage, Vin is the input voltage, and G is the gain.
The recommended input impedance for the INA103KU is ≥1kΩ to ensure accurate operation. A higher input impedance can lead to reduced accuracy and increased noise sensitivity.
