INA194AIDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Output voltage representing shunt current with 300 kHz bandwidth, 1.5 Ω output impedance, and maximum 10 nF capacitive load. |
| 2 | GND | power_in | Ground reference. |
| 3 | VIN+ | power_in | Connection to supply side of shunt resistor with common-mode input voltage range −16 V to +80 V. |
| 4 | VIN- | power_in | Connection to load side of shunt resistor with common-mode input voltage range −16 V to +80 V. |
| 5 | V+ | power_in | Analog power supply with operating range 2.7 V to 18 V and maximum quiescent current 900 µA. |
