CT815x Integrated Omnipolar TMR Analog Sensors Allegro MicroSystems CT815x Integrated Omnipolar Tunnel Magnetoresistance (TMR) Analog Sensors provide a monolithic solution for superior sensing performance in consumer and industrial applications. The CT815x sensors offer magnetic operation over temperature and linear sample and hold (S&H) analog output voltage with a sampling frequency of 100Hz. For applications that require a very small form factor and low profile, the CT815x sensors are assembled in a 4-lead LGA package. The CT8150 is available in an industry-standard 3-lead SOT-23 package, while the CT8152 is offered in a 5-lead SOT-23 package to support high-volume manufacturing.
