INA199A2RSWT from Texas Instruments, in a UQFN-10(1.4x1.8). 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 | NC | unconnected | No internal connection; the pin may be left floating or connected to any voltage between GND and V+. |
| 2 | IN+ | input | Analog input connected to the supply side of the shunt resistor; both IN+ pins (2 and 3) must be connected together, and the absolute maximum input current is 5 mA per pin. |
| 3 | IN+ | input | Analog input connected to the supply side of the shunt resistor; must be connected together with pin 2, and the absolute maximum input current is 5 mA per pin. |
| 4 | IN- | input | Analog input connected to the load side of the shunt resistor; both IN- pins (4 and 5) must be connected together, with common-mode range -0.3 V to 26 V for the INA199Ax version. |
| 5 | IN- | input | Analog input connected to the load side of the shunt resistor; must be connected together with pin 4, with common-mode range -0.3 V to 26 V for the INA199Ax version. |
| 6 | V+ | power_in | Analog supply pin, specified for 2.7 V to 26 V with an absolute maximum supply of 26 V. |
| 7 | NC | unconnected | No internal connection; the pin may be left floating or connected to any voltage between GND and V+. |
| 8 | REF | input | Reference voltage input that must be set between 0 V and V+, and must be buffered by an op amp if driven from a resistor divider. |
| 9 | GND | power_in | Analog ground reference for the device. |
| 10 | OUT | output | Analog voltage output whose swing is limited by the V+ supply and GND, with absolute limits of GND - 0.3 V to (V+) + 0.3 V. |
