Description

The ACT001-10E is a high-linearity, extremely low-hysteresis current sensor manufactured with NVE’s

state-of-the-art tunneling magnetoresistance (TMR) technology. The sensor has an on-chip current strap

close to TMR sensor elements that enable highly sensitive and accurate measurements. The sensor output is a

bipolar voltage signal proportional to the current through the strap.
