Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-

tended 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, 1.5 k

Ω in series with 100 pF.

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 TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is

PD = (TJ(max) −TA)/θJA. All numbers apply for packages soldered directly into a PC board.

Note 5: Typical values represent the most likely parametric norm.

Note 6: All limits are guaranteed by testing or statistical analysis.

Note 7: CMRR measured at VCM = 0V to 2.5V and 2.5V to 5V when VS = 5V, VCM = 0.2V to 1.35V and 1.35V to 2.7V when VS = 2.7V. This eliminates units that

have large VOS at the VCM extremes and low or opposite VOS at VCM = VS/2.

Note 8: All measurements made at 10 kHz. A 100 k

Ω pull-up resistor was used when measuring the LMC7225. CLOAD = 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.
