The NCS21xR (AEC- Q100 qualified) are voltage output, current sense amplifiers that can measure voltage across shunts at common−mode voltages from −0.3 V to 26 V, independent of supply voltage. With a fixed gain, the low offset of the zero−drift architecture enables current sensing across the shunt with maximum voltage drops as low as 10 mV full−scale. These devices can operate from a single +2.2 V to +26 V power supply, drawing a maximum of 80 µA of supply current. Available in SC70-6 package.

Available tools

Customer evaluation board for the NCS21xR series of current sense amplifiers. These easy to use, straightforward customer evaluation board allows customers to quickly observe the performance and measure key parameters. The PCB comes populated with the DUT, six test points, and one 0.1 µF cap for C1. The R1 resistor is left unpopulated so that the customer can connect either two voltage potentials at the inputs, or their own custom shunt resistor style and value for quick prototyping. The part is linked to the EVB webpage.
