The A1262 2D dual-channel Hall-effect sensor IC is offered in a 5-pin SOT23W surface-mount package, as well as a 4-pin SIP through-hole package. It features operation with traditional planar—as well as vertical—magnetic field direction.Learn More
AN296233 - Electrical interfaces for active sensor integrated circuits (ICs) include both two-wire and three-wire interfaces. These two technology styles are named for the number of required connections needed to communicate the sensor output. This application note discusses use and tradeoffs of ...Learn More
There are four general categories of Hall-effect IC devices that provide a digital output: unipolar switches, bipolar switches, omnipolar switches, and latches. Latching Hall-effect sensor ICs, often referred to as "latches," are digital output Hall-effect switches that latch output states.Learn More
