2.7V Electrical Characteristics (continued)
Unless otherwise specified, all limits ensured for TJ = 25°C, V+ = 2.7V, V− = 0V, VCM = VO = V+/2. Boldface limits apply at the
temperature extremes.

(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 ensured on shipped
production material.
(2) All limits are specified by testing or statistical analysis.
(3) CL includes the probe and test jig capacitance.
