Electrical Characteristics: V_S = 5 V (continued)
Test conditions are at T_A = 25°C, VS+ = 2.5 V, VS– = –2.5 V, V_CM = 0 V, R_L = 200-Ω differential, G = 16 dB, single-ended
input and differential output, and input and output referenced to midsupply, unless otherwise noted. Measured using an
evaluation module (EVM) as discussed in the section.
