INA290A2IDCKT from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Output voltage of the current-sense amplifier, which must stay between GND - 0.3 V and VS + 0.3 V per the absolute maximum ratings. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | VS | power_in | Power supply pin with a recommended operating range of 2.7 V to 20 V and an absolute maximum of 22 V. |
| 4 | IN+ | input | Current-sense amplifier positive input, connected to the supply side of the shunt resistor, with analog input common-mode limits of -20 V to 122 V. |
| 5 | IN- | input | Current-sense amplifier negative input, connected to the load side of the shunt resistor, with analog input common-mode limits of -20 V to 122 V. |
