The Hall Current 5 Click Board™ is a very accurate electric current measurement Click Board™ based on the ACS733 IC. This IC is a galvanically isolated current sensor, which utilizes the Hall-effect principle. Its most distinctive feature is its very low series resistance of only 1 mΩ, which makes this device a nearly-perfect ammeter. The maximum current which can be measured with the Hall Current 5 Click Board™ ranges from -20 A to +20 A, with the optimised precision. By using the latest manufacturing technologies, the ACS733 can be used on very high frequencies, making it a perfect solution for a wide range of applications.
