ELECTRICAL CHARACTERISTICS
(Circuit of Figure 2, VIN = 12V, VCC = VDD = VIN3 = SHDN = PGD_IN = 5V, VDDIO = 1.8V, OPTION = GNDS_ = AGND = PGND,
FBDC_ = FBAC_ = OUT3 = CSP_ = CSN_ = 1.2V, all DAC codes set to the 1.2V code, TA = -40°C to +105°C, unless otherwise
noted. Typical values are at TA = +25°C.) (Note 5)
