8.3.2 EMI Rejection

The OPAx180 family uses integrated electromagnetic interference (EMI) filtering to reduce the effects of EMI interference from sources such as wireless communications and densely populated boards with a mix of analog signal chain and digital components. EMI immunity can improve with circuit design techniques; the OPAx180 family benefits from these design improvements. Texas Instruments has developed the ability to accurately measure and quantify the immunity of an operational amplifier over a broad frequency spectrum extending from 10 MHz to 6 GHz. Figure 25 shows the results of this testing on the OPAx180 family . For more detailed information, see the EMI Rejection Ratio of Operational Amplifiers application report, available for download from www.ti.com.
