ADC141S626 Converter Electrical Characteristics (Note 7)
The following specifications apply for V_A = V_IO = V_REF = +2.7V to 5.5V and f_SCLK = 0.9 to 3.6 MHz or V_A = V_IO = V_REF = +4.5V to
5.5V and f_SCLK = 3.6 to 4.5 MHz; f_IN = 20 kHz and C_L = 25 pF, unless otherwise noted. Boldface limits apply for T_A = T_MIN to
T_MAX; all other limits are at T_A = 25°C.
