(1) 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 specified on shipped
production material.
(2) 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.
