(1) Typical values represent the most likely parametric normal.
(2) When operated at temperature between –40°C and 85°C, the LMC7101Q-Q1 will meet LMC7101BI specifications.
(3) V⁺ = 15 V. Connected as a voltage follower with a 10-V step input. Number specified is the slower of the positive and negative slew
rates. R_L = 100 kΩ connected to 7.5 V. Amplifier excited with 1 kHz to produce V_O = 10 V_PP.
