(1) All limits are guaranteed by design, test and/or statistical analysis. All electrical characteristics having room-temperature limits are tested during production with TA = 25M C. All hot and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control. (2) Capacitors: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) are used in setting electrical characteristics. (3) Specification ensured by design. Not tested during production.
