Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Electrical Characteristics
(VRS+ = VRS- = VCC = 2.7V to 24V, VSENSE = VRS+ - VRS- = 0V, IREFOUT = 0, VSHDN = VCC, VGSEL = GND, VREFIN = 2.5V
(MAX4072), TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C and at VCC = VRS+ = 12V.) (Notes 1, 2)
