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 kΩ 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)−T A)/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. 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 kΩ 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. www.national.com 4
