SBOS499B
– JANUARY 2011 – REVISED FEBRUARY 2011
ELECTRICAL CHARACTERISTICS: VS = +12V
Boldface limits are tested at +25
°C.
At TA = +25°C, with RMATCH = 10.2, transformer turn ratio 1:1.4, RL = 100 differential at transformer output, Full Bias Mode,
and active impedance circuit configuration, unless otherwise noted. Each port is tested independently.
