7.3.3 EMI Rejection

The INA500 uses integrated electromagnetic interference (EMI) filtering to reduce the effects of EMI from sources such as wireless communications and densely-populated boards with a mix of analog signal chain and digital components. EMI immunity can be improved with circuit design techniques; the INA500 benefits from these design improvements. Texas Instruments has the ability to accurately measure and quantify the immunity of an operational amplifier over a broad frequency spectrum extending from 10MHz to 6GHz. Figure 7-81 shows the results of this testing on the INA500 for differential EMI interference and Figure 7-5 shows the results of this testing on the INA500 for common-mode EMI interference. Table 7-2 provides the EMIRR IN+ values for the INA500 at particular frequencies commonly encountered in real-world applications. The EMI Rejection Ratio of Operational Amplifiers application report contains detailed information on the topic of EMIRR performance relating to op amps and is available for download from www.ti.com.
