MARKING DIAGRAMS
8
The NCS7041 and NCV7041 are high voltage, high resolution,
current sense amplifiers. They feature gain options of 14, 20, 50, and
100 V/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 have a wide common mode
input voltage range 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.
