Note 1: The LTC1629-PG is tested in a feedback loop that servos VITH to a specified voltage and measures the resultant VEAIN. Wafer level testing is performed per the indicated specifications for dice. Considerable differences in performance can often be observed for dice versus packaged units due to the influences of packaging and assembly on certain devices and/or parameters. Please consult factory for more information on dice performance and lot qualifications via lot sampling test procedures. Dice data sheet subject to change. Please consult factory for current revision in production.
