[5] Used recommended OpAmp bias settings (Reg 02h[1:0]) in Table 9. [6] OIP3 and OIP2 measured from 100 Ω differential source into 400 Ω differential load. Used recommended OpAmp bias settings (Reg 02h[1:0]) in Table 9. OIP3 and OIP2 measurements can be translated from dBm into dBVrms as follows: IPx [dBVrms] = IPx [dBm] -4 dB.
