Over temperature limits set by characterization and simulation. (B) Limits set by characterization and simulation. (C) Typical value only for information. (2) Not directly measurable; calculated using noise gain of 101 as described in the Applications section, Audio Performance. (3) Input offset voltage drift, input bias current drift, input offset current drift, and VOCM drift are average values calculated by taking data at the maximum-range ambient-temperature end points, computing the difference, and dividing by the temperature range. Maximum drift is set by the distribution of a large sampling of devices. Drift is not specified by a test or a quality assurance (QA) sample test. (4) Input bias current is positive out of the device. 8 Submit Documentation Feedback Copyright © 2008–2015, Texas Instruments Incorporated Product Folder Links: THS4521 THS4522 THS4524 |
