Note 1: Adjustable to zero.
Note 2: With 50ω fixed resistor from REFOUT to BIPOFF. Adjustable to zero.
Note 3: With 50ω fixed resistor from REFOUT to REFIN. Adjustable to zero.
Note 4: Maximum change in specification from TA = +25°C to TMIN or TA = +25°C to TMAX.
Note 5: External load current should not change during a conversion. For Q12V supply operation, REFOUT need not be buffered
except when external load in addition to REFIN and BIPOFF inputs have to be driven.
