... GND. The MAX4071 is similar, but with a refer- ence voltage of 1.5V. The MAX4069 has an adjustable reference voltage, set by two external resistors. The MAX4072 has an input for an external reference. The MAX4069/MAX4071/MAX4072 operate from a 2.7V to 24V single supply. The MAX4070 operates from a 3.6V to 24V single supply. All devices are specified over the automotive operating temperature range, -40° ...

... These capaci- tors are not required for operation or stability and their use does not degrade performance. The MAX4069–MAX4072 have been designed as a high- side current monitor to ease the task of grounding any battery charger, thermistor, etc., that may be a part of the battery pack. Grounding these devices requires no special precautions ...
