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 Inf F or o m r p atio r n ifc ur e n , d ishe e d lbiv y e A r n y a alog n D d t evic o p es is la beclie o eved rd to ebre sa: H ccur iattti e tae M nd re ilicarbloew .
