Product Description
Product Overview
The Allegro CT100 is a 1D linear sensor featuring Allegro's patented XtremeSense TMR technology in a full-bridge configuration. It offers a wide magnetic field range of 50 mT, achieving 0.5% linearity error from 20 mT to +20 mT. The CT100 excels in temperature stability across its full operating range and supports a broad supply voltage from 1.0 V to 5.5 V. Available in compact 6-lead SOT23 and low-profile 6-lead DFN packages, as well as die form, it is ideal for space-critical applications. The device is suitable for linear measurements, proximity sensing, and current sensing applications.
