Figure 33. OPA167x EMIRR vs Frequency
Table 1 lists the EMIRR IN+ values for the OPA167x at particular frequencies commonly encountered in real-
world applications. Applications listed in Table 1 can be centered on or operated near the particular frequency
shown. This information can be of special interest to designers working with these types of applications, or
working in other fields likely to encounter RF interference from broad sources, such as the industrial, scientific,
and medical (ISM) radio band.
