Datasheet

Note 2: Parameters are 100% production tested at +25°C, limits over temperature are guaranteed by design.
Note 3: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
ground, unless otherwise noted.
Note 4: V
CM
is the common-mode input voltage. V
ID
is the differential input voltage.
Note 5: Not production tested. Guaranteed by design.
