INA240A4EDRQ1 from Texas Instruments, in a SOIC-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 | Negative differential input; connected to load side of shunt resistor for current measurement |
| 2 | GND | power_in | Analog ground reference; 0V reference for all circuits |
| 3 | REF2 | input | Reference 2 voltage input; connect to 0V to VS to adjust output midpoint for single or dual-directional current measurement |
| 4 | NC | unconnected | No connection; pin not connected to internal circuit; may be grounded or left floating |
| 5 | OUT | output | Analog output voltage; output range limited by supply voltage VS with 50mV minimum above GND and 200mV minimum below VS |
| 6 | VS | power_in | Power supply voltage; operating range 2.7V to 5.5V, supports single supply operation |
| 7 | REF1 | input | Reference 1 voltage input; connect to 0V to VS to adjust output midpoint for single or dual-directional current measurement |
| 8 | IN+ | input | Positive differential input; connected to power side of shunt resistor for current measurement; differential range ±80V maximum |
