ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. Unless otherwise specied, VDCIN = VDCOUT = VDCDIV = 12V, VBAT = 8.4V,
GND = SGND = CLP = CLN = SHDN = 0V and RVREF = 49.9k. All currents into device pins are positive and all currents out of device pins
are negative. All voltages are referenced to GND, unless otherwise specied.
