(2) To ensure accuracy, it is required that VA, VTC, VE and VDR be well bypassed. Each supply pin must be decoupled with separate bypass capacitors.
(3) Typical figures are at TA = 25°C, and represent most likely parametric norms. Test limits are ensured to Texas Instrument's average outgoing quality level (AOQL).
