Feature Description (continued)

If available, any dual and quad operational amplifier device versions have nearly similar EMIRR IN+

performance. The OPA207 unity-gain bandwidth is 1 MHz. EMIRR performance below this frequency denotes

interfering signals that fall within the operational amplifier bandwidth.

Table 1 shows the EMIRR IN+ values for the OPA207 at particular frequencies commonly encountered in real-

world applications. Applications listed in Table 1 may be centered on or operated near the particular frequency

shown. This information may 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.

7.4 Device Functional Modes

The OPA207 has a single functional mode and is operational when the power-supply voltage is greater than 4.5

V (± 2.25 V). The maximum power supply voltage for the OPA207 is 36 V (±18 V).
