The integrated current-sensing resistor ensures measurement stability over temperature as well as simplifying printed-circuit board (PCB) layout difficulties common in high precision current sensing measurements. The onboard current-sensing resistor is designed as a 4-wire (or Kelvin) connected resistor that enables accurate measurements through a force-sense connection. The Kelvin connections to the shunt are done internally eliminating many of the parasitic impedances commonly found in typical very-low sensing-resistor level measurements. Although the shunt resistor can be accessed through the IN+ and IN– pins, this resistor is not intended to be used as a stand-alone component. The INA260 is internally calibrated to ensure that the current sensing resistor and current-sensing amplifier are both precisely matched to one another. The INA260 has approximately 4.5 mΩ of total resistance between the IN+ and IN- pins. 2 mΩ of this total package resistance is a precisely-controlled resistance from the Kelvin-connected current-sensing resistor used by the internal analog to digital converter (ADC). The power dissipation requirements of the system and package are based on the total 4.5-mΩ package resistance. The heat dissipated across the package when current flows through the device ultimately determines the maximum current that can be safely handled by the package. The current consumption of the silicon is relatively low, leaving the total package resistance carrying the high load current as the primary contributor to the total power dissipation of the package. The maximum safe-operating current level is set to ensure that the heat dissipated across the package is limited so that no damage to the resistor or the package itself occurs or that the internal junction temperature of the silicon does not exceed a 150°C limit.\u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47242281484460,"sku":"S138","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/S138.jpg?v=1789724049","url":"https:\/\/dotfry.com\/products\/precision-digital-current-and-power-monitor-using-ina260","provider":"dotfry","version":"1.0","type":"link"}
