SBOS499C â JANUARY 2011 â REVISED APRIL 2011
ELECTRICAL CHARACTERISTICS: VS = +12V
Boldface limits are tested at +25°C.
At TA = +25°C, with RMATCH = 10.2â¦, 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.

(1) Test levels: (A) 100% tested at +25°C. Over temperature limits set by characterization and simulation. (B) Limits set by characterization
and simulation. (C) Typical value only for information.
(2) Negative feedback loop only.
(3) Measured at amplifier output (pin 17, 20, 21, and 24).
(4) Capacitor fully charged, no droop.
