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:

TA = -40°C to +85°C, VIN = 3.6V, EN = VDD, unless otherwise noted. Typical values are at

TA = +25°C. Boldface limits apply over the operating temperature range,

-40°C to +85°C. (Continued)
