AG905-07
Evaluation board for current sensor AAT025
The AG905 evaluation board is used to test the NVE AAT025 current sensor.
It is a four-layer PCB designed for maximum current carrying capacity at low cost. Current flows through strong traces on the bottom and inner layers, minimizing overall resistance at low temperature rises. Thermal vias connect the trace layers together to reduce resistance and aid cooling. The inner layers are electrically insulated from the traces and extract heat from them due to the high thermal conductivity. By passing the sensing current through 3 layers, heating is minimized and heat spreads easily through the PCB to aid cooling.

Under the brand name IsoLoop, NVE has developed several series of couplers and transceivers for high-speed data transmission on a magnetic basis.
NVE Corporation is a leader in the practical commercialization of spintronics, a nanotechnology that relies on electron spin rather than electron charge to acquire, store and transmit information.
The company manufactures high-performance spintronic products including sensors and couplers that are used to acquire and transmit data. Products offer smaller size, more precision, higher speed, and are more rugged than coventional devices. NVE parts are popular in industrial, scientific, and medical applications. Sensors acquire information, couplers transmit information, and memories store information. Thus our technology can provide the eyes, nerves, and brains of electronic systems. NVE's award-winning products are sold through a worldwide distribution network.
NVE was founded by Dr. James M. Daughton, a former Honeywell executive, in 1989. The company is located in Eden Prairie, Minnesota, a suburb of Minneapolis.
