Description
AI
The NCS(V)7030 and NCS(V)7031 are high voltage, current sense amplifiers. They are available with gain options of 14 V/V and 20 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. The current sense amplifiers offer excellent input common−mode rejection from −6 V to 80 V. They can perform unidirectional 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.Similar Products:
