Shown here are the results of the four international noise tests. Unparalleled noise immunity was achieved in each of the tests for radio wave emission, near field immunity, BCI, and DPI. The radio wave emission, near field immunity, and BCI tests evaluate how much the output fluctuates in response to an input noise signal. ROHM’s op amps, indicated by the red lines, show a level of stability surpassing that of the competition. The DPI test on the lower right compares the amount of input power required to achieve an output fluctuation of 300 mV, making it clear that ROHM’s op amps, which require a larger amount of power to achieve a 300 mV output fluctuation, deliver significant advantages when compared to other products.
