3163

This Hall-effect switch is a monolithic integrated circuit designed to operate continuously over extended temperatures to +85°C.  The unipo- lar switching characteristic makes this device ideal for use with a simple bar or rod magnet.  The A3163ELT and A3163EUA are identical except for package.

3163 includes a voltage regulator for operation with supply voltages of 3.5 to 24 volts, reverse-battery protection, quadratic Hall- voltage generator for low offset, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and a constant-current open- collector output, wired internally for true 2-wire operation.  Noise radiation is limited by control of the output-current slew rate.
