ISL8014A
Electrical Specifications Unless otherwise noted, all parameter limits are established across the recommended operating conditions and
the typical specification are measured at the following conditions unless otherwise noted: TA = -40°C to +85°C, VIN = 3.6V, EN = VDD. Typical values are
at TA = +25°C. Boldface limits apply across the operating temperature range, -40°C to +85°C. (Continued)
