6.3.2 EMI Rejection

The TLV916x 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 TLV916x 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

6-3 shows the results of this testing on the TLV916x. Table 6-1 lists the EMIRR IN+ values for the TLV916x 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.
