ELECTRICAL CHARACTERISTICS: V_S = +12V (continued)
Boldface limits are tested at +25°C.
At T_A = +25°C, with R_MATCH = 10.2Ω, transformer turn ratio 1:1.4, R_L = 100Ω differential at transformer output, Full Bias Mode,
and active impedance circuit configuration, unless otherwise noted. Each port is tested independently.
