INA241A1IDDFR from Texas Instruments, in a SOT-23-8. 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 | IN- | input | Current sense amplifier negative input for differential voltage measurement; common-mode input voltage range -5V to +110V. |
| 2 | GND | power_in | Device ground reference and return path for all circuits. |
| 3 | REF2 | input | Reference 2 voltage input; accepts 0V to VS for setting output voltage baseline per gain equation. |
| 4 | NC | unconnected | Reserved no-connect pin; must be connected to ground per datasheet. |
| 5 | OUT | output | Analog output voltage with swing from GND+20mV to VS-200mV representing amplified differential current sense signal. |
| 6 | VS | power_in | Positive power supply input; accepts 2.7V to 20V for device bias and output stage operation. |
| 7 | REF1 | input | Reference 1 voltage input; accepts 0V to VS for setting output voltage baseline per gain equation. |
| 8 | IN+ | input | Current sense amplifier positive input for differential voltage measurement; common-mode input voltage range -5V to +110V. |
