ELECTRICAL CHARACTERISTICS (continued)
(V_DD = 2.7V to 3.6V (MAX11613/MAX11615/MAX11617), V_DD = 4.5V to 5.5V (MAX11612/MAX11614/MAX11616), V_REF = 2.048V
(MAX11613/MAX11615/MAX11617), V_REF = 4.096V (MAX11612/MAX11614/MAX11616), f_SCL = 1.7MHz, T_A = T_MIN to T_MAX, unless
otherwise noted. Typical values are at T_A = +25°C, see Tables 1–5 for programming notation.)
