High EMI Immunity Op Amps & Ultra-Low noise CMOS Op Amps
■As the demand for sensors increases in automotive systems and industrial equipment, so does the need for sensing circuits that operate safely and with high accuracy.
■In sensing circuits, how to process the weak electrical signals output by sensor elements can significantly affect safety and performance.
■This requires an Op Amp for amplifying the signal to a level that the system can accurately process. When an Op Amp amplifies weak signals, external noise from other devices as well as semiconductor noise emitted from the Op Amp itself can cause interference, but the pursuit for noise immunity invariably puts a limit on performance.
■ROHM has succeeded in commercializing high performance Op Amps that exceed the limits of existing noise performance by leveraging integrated manufacturing and reviewing not only circuit design but also layout, processes, and element variations.
