(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, V_CM = 1.5 V and R_L connect to 7.5 V. For sourcing tests, 7.5 V ≤ V_O ≤ 12.5 V. For sinking tests, 2.5 V ≤ V_O ≤ 7.5 V.
