NCx703x Unidirectional Current Sense Amplifiers

onsemi NCx703x Unidirectional Current Sense Amplifiers are high-voltage current sense amplifiers designed for precise current measurement in various applications. The onsemi NCx703x includes the NCS7030, NCS7031, NCV7030, and NCV7031 devices. These amplifiers offer excellent input common-mode rejection from -6V to 80V, ensuring accurate performance even in challenging environments. Available with gain options of 14V/V and 20V/V, the components maintain a maximum gain error of ±0.3% over the entire temperature range. The NCx703x amplifiers are ideal for automotive and industrial applications, providing reliable current sensing across a sense resistor. Additionally, these amplifiers are available in compact SOIC-8 and Micro8 packages, making them suitable for space-constrained designs.
