NCS7041

NCS7041 is a high voltage, high resolution, current sense amplifier. It consists of a preamplifier and buffer with access to output and input via A1 and A2 pins for an intermediate filter network or modified gain. This part has a wide common mode input voltage range from -6V to 80V. The NCS7041 can perform unidirectional or bidirectional current measurements across a sense resistor in a variety of applications. Applications include telecom equipment, power supply designs, diesel injection control, automotive, solenoids/actuators.
