6.3.1 EMI Rejection

The TLV910x-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, and the TLV910x-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 6-1 shows the results of this testing on the TLV910x-Q1. Table 6-1 shows the EMIRR IN+ values for the TLV910x-Q1 at particular frequencies commonly encountered in real-world applications. Table 6-1 lists applications that can be centered on or operated near the particular frequency shown. The EMI Rejection Ratio of Operational Amplifiers application report contains detailed information on the topic of EMIRR performance of op amps and is available for download from www.ti.com.
