After offset compensation has been performed. 2. The amplifier accuracy is dependent on the environment. The offset value is given for a measurement done with all digital I/Os stable. Negative injection current on the I/Os close to the inputs may reduce the accuracy. In particular care must be taken to avoid switching on I/Os close to the inputs when the op-amp is in use. This phenomenon is even more critical when a big external serial resistor is added on the inputs. 3. The data are provided from simulations (not tested in production) to guide the user when re-calibration is needed. 4. Data based on characterization results, not tested in production. 5. AVCL = closed loop gain. 6. The data are provided from simulations (not tested in production). Obsolete Product(s) - Obsolete Product(s) |
