4 / 17 page  ADATE209 Rev. A | Page 3 of 16 SPECIFICATIONS ELECTRICAL CHARACTERISTICS VCC = 7.0 V, VEE = −4.5 V, GND = 0.0 V; all test conditions are as defined in Table 8, unless otherwise specified. All specified values are at TJ = 70°C, where TJ corresponds to the internal temperature sensor, unless otherwise noted. Temperature coefficients are measured at TJ = 70°C ± 20°C, unless otherwise noted. Typical values are based on design, simulation analyses, and/or limited bench evaluations. Typical values are not tested or guaranteed. Table 1.
