2.7V to 5V Electrical Characteristics (Continued)
Unless otherwise specified, all limits guaranteed for T_J = 25˚C, V⁺ = 2.7V to 5V, V^− = 0V, V_CM = V_O = V⁺/2. Boldface limits
apply at the temperature extremes.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std. JESD22-A115-A (ESD MM std. of JEDEC)
Field-Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC).
Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C.
Note 4: The maximum power dissipation is a function of T_J(MAX), θ_JA, and T_A. The maximum allowable power dissipation at any ambient temperature is
P_D = (T_J(MAX) − T_A)/θ_JA. All numbers apply for packages soldered directly into a PC board.
Note 5: Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will
also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material.
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: CMRR measured at V_CM = 0V to 2.5V and 2.5V to 5V when V_S = 5V, V_CM = 0.2V to 1.35V and 1.35V to 2.7V when V_S = 2.7V. This eliminates units that
have large V_OS at the V_CM extremes and low or opposite V_OS at V_CM = V_S/2.
Note 8: All measurements made at 10 kHz. A 100 kΩ pull-up resistor was used when measuring the LMC7225. C_LOAD = 50 pF including the test jig and scope
probe. The rise times of the LMC7225 are a function of the R-C time constant.
Note 9: Input step voltage for the propagation measurements is 100 mV.
Note 10: Do not short the output of the LMC7225 to voltages greater than 10V or damage may occur.
