## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Output voltage pin; the absolute maximum output range is GND − 0.3 V to Vs + 0.3 V. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | IN+ | input | Shunt resistor positive sense input; operational common-mode range is −4 V to +110 V and survival range is −20 V to +120 V. |
| 4 | IN- | input | Shunt resistor negative sense input; for the INA293A5 the differential input (VIN+) − (VIN−) absolute maximum is −6 V to 6 V. |
| 5 | Vs | power_in | Power supply pin; the device operates from a single 2.7-V to 20-V supply with an absolute maximum supply voltage of −0.3 V to 22 V. |
