ELECTRICAL CHARACTERISTICS (continued)
Test conditions are at T_A = +25°C, V_S+ = +5V, V_OCM = +2.5V, V_OUT = 2V_PP, R_L = 400Ω differential, G = +12dB, differential input
and output, and input and output referenced to midsupply, unless otherwise noted. Measured using evaluation module as
discussed in Test Circuits section.
