ELECTRICAL CHARACTERISTICS—MAX472
(VCC = +3V to +36V, RG1 = RG2 = 200, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
Note 2: VOS is defined as the input voltage (VSENSE) required to give minimum IOUT.
Note 3: VSENSE is the voltage across the sense resistor.
VSHDN = 2.4V
