INA293B3QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 representing the amplified differential voltage across the shunt resistor, with output swing from GND + 0.005 V to 0.02 V at minimum current and Vs - 0.07 V to Vs - 0.15 V at maximum current. |
| 2 | GND | power_in | Ground reference for the device power supply and output stage. |
| 3 | Vs | power_in | Power supply voltage input with operating range 2.7 V to 20 V and absolute maximum rating of -0.3 V to 22 V. |
| 4 | IN+ | input | Shunt resistor positive sense input for differential voltage measurement; part of differential pair with maximum ±12 V differential input and common-mode range -4 V to +110 V. |
| 5 | IN- | input | Shunt resistor negative sense input for differential voltage measurement; part of differential pair with maximum ±12 V differential input and common-mode range -4 V to +110 V. |
