SM73201 Converter Electrical Characteristics (Note 7)
The following specifications apply for VA = 4.5V to 5.5V, VIO = 2.7V to 5.5V, and VREF = 2.5V to 5.5V for fSCLK = 1 MHz to 4 MHz
or VREF = 4.5V to 5.5V for fSCLK = 1 MHz to 5 MHz; fIN = 20 kHz, and CL = 25 pF, unless otherwise noted. Maximum and minimum
values apply for TA = TMIN to TMAX; the typical values apply for TA = 25°C.
