The maximum voltage that can be applied to the input pins is ±40V, but it's recommended to keep it within ±20V for optimal performance and to prevent damage to the device.
To ensure accurate current measurements, make sure to use a sense resistor with a low temperature coefficient, keep the sense resistor close to the INA200, and use a low-noise power supply. Also, ensure that the input voltage is within the recommended range and that the device is operated within its specified temperature range.
The CAP pin is used to connect a capacitor to filter out high-frequency noise and improve the accuracy of the current measurement. A 10nF to 100nF capacitor is recommended, but the optimal value depends on the specific application and noise environment.
The INA200 is designed to measure DC currents, but it can be used to measure AC currents with some limitations. The device can measure AC currents up to 100 kHz, but the accuracy may degrade at higher frequencies. Additionally, the sense resistor should be chosen to minimize the voltage drop and ensure accurate measurements.
The power consumption of the INA200 can be calculated using the formula: Power (mW) = (VCC x ICC) + (VIN x IIN), where VCC is the supply voltage, ICC is the quiescent current, VIN is the input voltage, and IIN is the input current. The typical power consumption is around 1.5mW, but it depends on the specific application and operating conditions.
