6.3.7 EMI Rejection

The TLV904x-Q1 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 TLV904x-Q1 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 10MHz to 6GHz. Figure 6-4 shows the results of this testing on the TLV904x-Q1. Table 6-1 shows the EMIRR IN+ values for the TLV904x-Q1 at particular frequencies commonly encountered in real-world applications. The EMI Rejection Ratio of Operational Amplifiers application note contains detailed information on how EMIRR performance relates to op amps and is available for download from www.ti.com.
