7.7 Typical Characteristics
At T_A = 25°C, split supplies, V_CM = 0 V, R_L = 200-Ω differential (R_OUT = 40 Ω each), G = 16 dB, single-ended input and
differential output, and input and output pins referenced to midsupply, unless otherwise noted. Measured using an EVM as
discussed in the Parameter Measurement Information section (see Figure 49 to Figure 53).
