The device includes on a single silicon chip a voltage regulator, quadratic Hall-voltage generator, temperature compensation circuit, signal amplifier, Schmitt trigger, and a buffered open-collector output to sink up to 25 mA. The on-board regulator permits operation with supply voltages of 4.5 volts to 24 volts. The first character of the part number suffix determines the device operating temperature range. Suffix `E' is for -40C to +85C, and suffix `L' is -40C to +150C. Two package styles provide a magnetically optimized package for most applications. Suffix `LT' is a miniature SOT89/TO-243AA transistor package for surface-mount applications while suffix `UA' is a three-lead ultra-mini-SIP.
