9 Power Supply Recommendations
The input circuitry of the INA280-Q1 device can accurately measure beyond the power-supply voltage. The
power supply can be 20 V, whereas the load power-supply voltage at IN+ and IN– can go up to 120 V. The
output voltage range of the OUT pin is limited by the voltage on the V S pin and the device swing to supply
specification.
10 Layout
10.1 Layout Guidelines
TI always recommends to follow good layout practices:
• Connect the input pins to the sensing resistor using a Kelvin or 4-wire connection. This connection technique
makes sure that only the current-sensing resistor impedance is detected between the input pins. Poor routing
of the current-sensing resistor commonly results in additional resistance present between the input pins.
Given the very low ohmic value of the current resistor, any additional high-current carrying impedance can
cause significant measurement errors.
• Place the power-supply bypass capacitor as close to the device power supply and ground pins as possible.
The recommended value of this bypass capacitor is 0.1 µF. Additional decoupling capacitance can be added
to compensate for noisy or high-impedance power supplies.
• When routing the connections from the current-sense resistor to the device, keep the trace lengths as short
as possible.
