differential), RL = 50
Ω
from +OUT to –OUT, unless otherwise noted. VBIAS is defi ned as the voltage on the VBIAS pin. VOUTCM is defi ned as (+OUT + –OUT)/2. VINCM is defi ned as (+IN + –IN)/2. VINDIFF is defi ned as (+IN – –IN). VOUTDIFF is defi ned as (+OUT – –OUT). See DC test circuit schematic. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
