3 / 36 page  ADP2116 Rev. 0 | Page 3 of 36 SPECIFICATIONS If unspecified, VDD = VINx = EN1 = EN2 = 5.0 V. The minimum and maximum specifications are valid for TJ = −40°C to +125°C, unless otherwise specified. Typical values are at TJ = 25°C. All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC). Table 1.
