(3) Full-scale reference (4) Post-calibration performance and no I/O changes during conversion with SRN as the ground reference. (5) Uncalibrated performance. This gain error can be eliminated with external calibration. (6) The A/D input is a switched-capacitor input. Since the input is switched, the effective input resistance is a measure of the average resistance. (7) Post-calibration performance (8) Reference voltage for the coulomb counter is typically Vref/3.969 at V(REG25) = 2.5 V, TA = 25°C. (9) Uncalibrated performance. This gain error can be eliminated with external calibration. Copyright © 2009, Texas Instruments Incorporated Submit Documentation Feedback 9 Product Folder Link(s): bq20z65-R1 |
