# INA290A5IDCKR

**Texas Instruments** · Current Sense Amplifiers · SC-70-5

INA290A5IDCKR 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 | Current-sense amplifier output voltage; the absolute maximum analog output range is GND - 0.3 V to VS + 0.3 V. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | VS | power_in | Power supply pin; the recommended operating supply range is 2.7 V to 20 V, with an absolute maximum supply of 22 V. |
| 4 | IN+ | input | Current-sense positive input, connected to the supply (bus-voltage) side of the shunt resistor; the analog input common-mode voltage is rated -20 V to 122 V absolute maximum. |
| 5 | IN- | input | Current-sense negative input, connected to the load side of the shunt resistor. |
