Typical Characteristics: (V_S+) – (V_S–) = 5 V (continued)
at T_A ≈ 25°C, VOCM pin = open, R_F = 1 kΩ, R_L = 1 kΩ, V_OUT = 2 V_PP, 50-Ω input match, G = 1 V/V, PD = V_S+, single-ended
input, differential output, and input and output referenced to default midsupply for ac-coupled tests (unless otherwise noted);
