Note :

1. AVCL = closed loop gain

2. Data based on characterization results, not tested in production.

3. after offset compensation has been performed.

4. The amplifier accuracy is dependent of 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 opamp is in use. This phenomenon is even more

critical when a big external serial resistor is added on the inputs.

5. The Data provided from simulations (not tested in production) to guide the user when re-calibration is needed.
