The CT81xx series of XtremeSense TMR magnetic sensors offer stable magnetic operation over the operating temperature range. With very high sensitivity, the CT81xx products enable larger air gaps or smaller size/lower cost magnets to be used in systems while also drawing supply current as low as 110 nA. As such, these magnetic sensors are ideal for battery operated products where minimal current consumption is required.
