Electrical Specifications
Unless otherwise noted, all parameter limits are established over the recommended
operating conditions and the typical specification are measured at the following conditions:
T A = -40°C to +85°C, V IN = 3.6V, EN = VDD, unless otherwise noted. Typical values are at
T A = +25°C. Boldface limits apply over the operating temperature range,
-40°C to +85°C. (Continued)
