The maximum input voltage that can be applied to the LM2917MX-8 is 40V, but it's recommended to keep it below 30V for reliable operation.
The sense resistor value depends on the maximum current you want to measure and the desired output voltage range. A good starting point is to use the formula Rsense = (Vout_max - Vout_min) / (Imax - Imin), where Vout_max and Vout_min are the maximum and minimum output voltage ranges, and Imax and Imin are the maximum and minimum current ranges.
The LM2917MX-8 has a temperature range of -40°C to 125°C, and its accuracy and performance may degrade at extreme temperatures. The device's offset voltage, gain, and linearity may vary by ±1% to ±5% over the temperature range, depending on the specific application and operating conditions.
The LM2917MX-8 is designed for DC current measurement, but it can be used to measure AC currents with some limitations. You'll need to add an external circuit to rectify the AC current and filter out any high-frequency noise. Additionally, the device's bandwidth and response time may not be suitable for high-frequency AC current measurements.
To minimize noise and ensure accurate measurements, follow good PCB layout practices such as separating the analog and digital grounds, using a solid ground plane, and keeping the sense lines as short and shielded as possible. Additionally, place the LM2917MX-8 close to the current sense resistor and use a low-impedance path for the sense lines.
