Product Overview
The CT815x series are omnipolar TMR analog sensors featuring Allegro's XtremeSense TMR technology integrated with CMOS for a monolithic solution. Designed for consumer and industrial applications, these sensors offer superior sensing performance with low power consumption, making them ideal for battery-operated devices. The CT815x series provides a linear sample-and-hold (S&H) analog output voltage at 100 Hz. The CT8152 variant uniquely combines both analog and digital outputs, utilizing the digital output to enable the analog output for ultra-low power states. Available in compact LGA and industry-standard SOT-23 packages, these sensors are suitable for applications requiring small form factors and high-volume manufacturing.
