range, otherwise specifications are at T
Note 1: Absolute maximum ratings are those values beyond which the life
of a device may be impaired.
Note 2: Linearity and monotonicity are defined from code k
2
rounded to the nearest whole code. For V
256 and linearity is defined from code 256 to code 65,535.
Note 3: Digital inputs at 0V or V
Note 4: Guaranteed by design and not production tested.
Note 5: Inferred from measurement at code 256 (LTC2606/LTC2606-1),
code 64 (LTC2616/LTC2616-1) or code 16 (LTC2626/LTC2626-1) and at
full scale.
