CT430 XtremeSense™ TMR Sensors

Allegro MicroSystems CT430 XtremeSense™ TMR Sensors are high bandwidth and ultra-low noise integrated contact current sensors. The Allegro CT430 utilizes the patented XtremeSense TMR technology to enable high-accuracy current measurements for many consumer and industrial applications. The CT430 Sensors support eight current ranges. The integrated current-carrying conductor (CCC) handles up to 65A of current and generates a current measurement as a linear analog output voltage. The device delivers a total output error of less than ±1.0% full-scale (FS) over-voltage and the full temperature range. The CT430 Sensors achieve 1MHz bandwidth and 300ns response time. High signal-to-noise (SNR) with ultra-low noise of 9mARMS. Integrated common-mode field rejection of -54 dB to ensure stray fields do not impact measurements in the working application.
