SBOS695A – AUGUST 2014 – REVISED DECEMBER 2014
Typical Characteristics (continued)
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).
