NCS7041DM3G050R2G

The NCS7041 and NCV7041 are high voltage, high resolution, current sense amplifiers. They feature gain options of 14, 20, 50, and 100 ΔV/V, with a maximum ±0.3% gain error over the entire temperature range. Each part 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. These parts offer excellent input common−mode rejection from -6 V to 80 V. The NCS7041 can perform unidirectional or bidirectional current measurements across a sense resistor in a variety of applications. Automotive qualified options are available under NCV prefix. All versions are specified over the extended operating temperature range from -40°C to 150°C.
