(1) Test levels (all values set by characterization and simulation): (A) 100% tested at TA ≈ 25°C; over temperature limits by characterization and simulation. (B) Not tested in production; limits set by characterization and simulation. (C) Typical value only for information.
(2) This slew rate is the average of the rising and falling time estimated from the large-signal bandwidth as: (VP / √ 2) · 2π · f–3dB.
(3) Input offset voltage drift, input bias current drift, input offset current drift, and Vocm drift are average values calculated by taking data at the at the maximum-range ambient-temperature end points, computing the difference, and dividing by the temperature range. Maximum drift set by distribution of a large sampling of devices. Drift is not specified by test or QA sample test.
(4) Specifications are from the input Vocm pin to the differential output average voltage.
