SLOS454H – JANUARY 2005 – REVISED NOVEMBER 2009
ELECTRICAL CHARACTERISTICS: V_S+ – V_S– = 5 V (continued)
Test conditions are at V_S+ = +2.5 V, V_S– = –2.5 V, G = 10 dB, CM = open, V_O = 2 V_PP, R_F = 349 Ω, R_L = 200-Ω differential,
T_A = +25°C, single-ended input, differential output, and input and output referenced to midsupply, unless otherwise noted.
