TDK Corporation and Asahi Kasei Microdevices Corporation (AKM) have jointly developed a highly accurate 3-axis magnetometer that combines an extremely sensitive tunnel magneto-resistive (TMR) element developed by TDK and an advanced electronic compass ASIC designed by AKM in a very small package. The new TMR magnetometer on a chip, which has miniature dimensions of just 1.6 mm x 1.6 mm x 0.6 mm, features the industry’s lowest RMS noise of just 40 nT-rms and a very low current consumption of only 40 µA at an output data rate of 100 Hz.
