SBOS237G – MARCH 2002 – REVISED MARCH 2010
ELECTRICAL CHARACTERISTICS: V_S = ±5V
Boldface limits are tested at +25°C.
At R_F = 402Ω for G = +2, (see Figure 36 for ac performance only), R_F = 25Ω for G = +1, and R_L = 100Ω, unless otherwise
noted.

(1) Test levels: (A) 100% tested at +25°C. Over temperature limits by characterization and simulation. (B) Limits set by characterization and
simulation. (C) Typical value only for information.
(2) Junction temperature = ambient for +25°C specifications.
(3) Junction temperature = ambient at low temperature limits; junction temperature = ambient +20°C at high temperature limit for over
temperature specifications.
(4) Current is considered positive out-of-node. V_CM is the input common-mode voltage.
(5) Tested < 3dB below minimum specified CMRR at ±CMIR limits.
