Pinout
1. IN+: Non-inverting input of the amplifier, connected to the high side of the shunt resistor.
2. IN-: Inverting input of the amplifier, connected to the low side of the shunt resistor.
3. VS: Power supply pin. This pin is connected to the power supply voltage, typically between 2.7 V and 5.5 V.
4. OUT: Output pin, where the amplified voltage representing the sensed current is available.
5. GND: Ground connection for the device, acting as the reference point for input and output signals.
6. REF: Reference voltage input, used to set the output voltage level when no differential input voltage is present.
These pins work together to accurately sense and amplify the voltage across a shunt resistor, providing a proportional output voltage.
