1. See Section 5.5 Input offset voltage drift over temperature. Input offset measurements are performed on
x100 gain configuration. The amplifiers and the gain setting resistors are at the same temperature.
2. Guaranteed by design.
3. Slew rate value is calculated as the average between positive and negative slew rates.
4. Initialization time is defined as the delay between the moment when supply voltage exceeds 2.2 V and
output voltage stabilization
