1. Typical values assume V
2. This current is a PGA module adder, in addition to and ADC conversion currents.
3. Between IN+ and IN-. The PGA draws a DC current from the input terminals. The magnitude of the DC current is a strong
4. Gain = 2
5. After changing the PGA gain setting, a minimum of 2 ADC+PGA conversions should be ignored.
