NIPPON CERAMIC CO., LTD.
SH 248 High Sensitivity CMOS Micropower Hall Switch
SH248 includes the following on a single silicon chip: voltage regulator, Hall voltage
generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short circuit protected
open-drain output. Advanced CMOS wafer fabrication processing is used to take advantage of
low-voltage requirements, component matching, very low input-offset errors, and small component
geometries.
