(1) Typical Values represent the most likely parametric norm.
(2) All limits are specified by testing or statistical analysis.
(3) Connected as Voltage Follower with 1.0V step input. Number specified is the slower of the positive slew rate. The negative slew rate is
faster. Input referred, V⁺ = 5V and R_L = 100 kΩ connected to 1.5V. Amp excited with 1 kHz to produce V_O = 1 V_PP.
10V DC Electrical Characteristics
Unless otherwise specified, all limits specified for T_J = 25°C, V⁺ = 10V, V^− = 0V, V_CM = V_O = V⁺/2 and R_L > 1 MΩ. Boldface
limits apply at the temperature extremes.
