6.1.3 Common-mode Range

The 10:1 input resistor ratio of the INA146 provides an input common-mode range that can extend well beyond the power supply rails. Exact range depends on the power supply voltage and the voltage applied to the Ref terminal (pin 1). For proper operation, the voltage at the non-inverting input of A1 (an internal node) must be within the linear operating range. The voltage is determined by the simple 10:1 voltage divider between pin 3 and pin 1. This voltage must be between V– and (V+) – 1 V.
