(2) The deviation of each output from the average of OUT0 to OUT15 constant-current. Deviation is calculated by the formula: (3) The deviation of the OUT0 to OUT15 constant-current average from the ideal constant-current value. Deviation is calculated by the formula: Ideal current is calculated by the formula: 4 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): TLC5929 |
