ELECTRICAL CHARACTERISTICS: V_S = ±5V
Boldface limits are tested at +25C.
At T_A = +25°C, G = +2V/V, R_F = 750Ω, and R_L = 150Ω to GND, unless otherwise noted (see Figure 70).

(1) Junction temperature = ambient for +25°C specifications.
(2) Junction temperature = ambient at low temperature limits; junction temperature = ambient +18°C at high temperature limit for over
temperature specifications.
(3) 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.
(4) Current is considered positive out of pin.
