1.4 Device Information

The INA750x current-sense amplifier comes with an integrated shunt resistor of 400μΩ. The INA750x is designed to monitor bidirectional current over a common-mode range of –4V to 110V, independent of the supply voltage. Adjustable gain option assists in optimizing the system dynamic range.

This device operates from a single 2.7V to 5.5V power supply, drawing a maximum of 3.75mA of supply current. All versions are specified over the extended operating temperature range (–40°C to +125°C), and are available in a 15-pin VQFN package

Table 1-2 lists the available sensitivity options.
