requires VCC slew rates to be no greater than 110mV/Вµs.
Note 4: Linearity and monotonicity are defined from code kL to code 2N–1,
where N is the resolution and kL is given by kL = 0.016(2N/ VFS), rounded
to the nearest whole code. For VFS = 2.5V and N = 12, kL = 26 and linearity
is defined from code 26 to code 4,095. For VFS = 4.096V and N = 12, kL =
16 and linearity is defined from code 16 to code 4,095.
Note 5: Inferred from measurement at code 16 (LTC2637-12), code 4
(LTC2637-10) or code 1 (LTC2637-8), and at full-scale.
Note 6: This IC includes current limiting that is intended to protect the
device during momentary overload conditions. Junction temperature can
exceed the rated maximum during current limiting. Continuous operation …
