8.3.4 EMI Rejection

The TLV674x 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 OPAx375 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 8-1 shows the results of this testing on the TLV674x. Table 8-1 shows the EMIRR IN+ values for the TLV674x 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 as it relates to op amps and is available for download from www.ti.com.
