9.2.1 Design Requirements

To allow for bidirectional monitoring, the INA303 requires a voltage applied to the REF pin. A voltage that is half of the supply voltage is usually preferred to allow for maximum output swing in both the positive and negative current direction. To reduce the errors in the reference voltage, drive the REF pin with a low-impedance source (such as an op amp or external reference). A low-value resistor divider can be used at the expense of quiescent current and accuracy. For this design, a single alert output is preferred, so both ALERT1 and ALERT2 are connected together and use a single pullup resistor.
