The output voltage on the fixed output versions will always be within the specified range. 3100 k Ω resistor connected between a 5 V source and the AO pin. 4 All limits at temperature extremes are guaranteed via correlation using standard statistical methods. Specifications subject to change without notice. (0 C ≤ TA ≤ +70 C, VIN = 3 V unless otherwise noted) REV. A |
