Table 1 Serial interface programming
Notes
1. PGA gain register must always be refreshed after clamp code register content has been changed.
2. When pin CLPADC = HIGH (SD1 = 1; serial interface), the ADC input is clamped to the voltage level of V
When the power supplies increase from zero to V
Table 2 Standby selection
Note
1. In case an external regulator is used, it has to be switched off in standby mode in order to avoid an extra power
