Feature Description (continued)
8.3.2 EMI Rejection
The OPAx191 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 OPAx191 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 53 shows the results of this testing on the OPAx191. Table 2 shows the EMIRR IN+ values for the
OPAx191 at particular frequencies commonly encountered in real-world applications. Applications listed in
Table 2 may be centered on or operated near the particular frequency shown. Detailed information can also be
found in the EMI Rejection Ratio of Operational Amplifiers application report , available for download from
www.ti.com.
PRF = –10 dBm, VS = ±15 V, VCM = 0 V
