DC Electrical Characteristics
Unless otherwise specified, all limits ensured for T_J = 25°C. Boldface limits apply at the temperature extremes. V⁺ = 5V, V^− =
0V, V_CM = 1.5V, V_O = 2.5V and R_L > 1M unless otherwise specified.

(1) Typical values represent the most likely parametric norm. Limits are specified by testing or correlation.
(2) V⁺ = 15V, V_CM = 7.5V and R_L connected to 7.5V. For Sourcing tests, 7.5V ≤ V_O ≤ 11.5V. For Sinking tests, 2.5V ≤ V_O ≤ 7.5V.
