# INA290A1IDCKR

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

INA290A1IDCKR 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 amplified from input differential voltage by fixed gain; output swing range GND + 0.005V to VS - 0.07V (typical). |
| 2 | GND | power_in | Ground reference connection. |
| 3 | VS | power_in | Power supply input with recommended operating range 2.7V to 20V. |
| 4 | IN+ | input | Current-sense amplifier positive input connected to supply-side of sense resistor with operating common-mode range 2.7V to 120V. |
| 5 | IN- | input | Current-sense amplifier negative input connected to load-side of sense resistor; accepts differential input voltage up to ±1.0V for A1 device. |
