4 / 27 page  ADC141S625 SNAS434A – NOVEMBER 2007 – REVISED JANUARY 2009 www.ti.com ADC141S626 Converter Electrical Characteristics (1) The following specifications apply for VA = VIO = VREF = +2.7V to 5.5V and fSCLK = 0.9 to 3.6 MHz or VA = VIO = VREF = +4.5V to 5.5V and fSCLK = 3.6 to 4.5 MHz; fIN = 20 kHz and CL = 25 pF, unless otherwise noted. Boldface limits apply for TA = TMIN to TMAX; all other limits are at TA = 25°C.
