INA199B2DCKR from Texas Instruments, in a SOT-363-6. 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 | REF | input | Reference voltage input, 0 V to V+. Sets the output-voltage level that corresponds to zero differential input (VSENSE = 0), enabling bidirectional current sensing when biased to mid-supply (typically VS/2). |
| 2 | GND | power_in | Analog ground return for the device. |
| 3 | V+ | power_in | Analog power supply, 2.7 V to 26 V (absolute max 26 V). Independent of the sensed common-mode input voltage. |
| 4 | IN+ | input | Non-inverting analog input; connect to the supply side of the external shunt resistor. Common-mode range -0.1 V to 26 V for the B version, independent of V+. |
| 5 | IN- | input | Inverting analog input; connect to the load side of the external shunt resistor. Common-mode range -0.1 V to 26 V for the B version, independent of V+. |
| 6 | OUT | output | Analog voltage output. VOUT = REF + Gain × (VIN+ - VIN-); Gain = 100 V/V for the INA199B2. Swings to within 50 mV of V+ and 5 mV of GND with a 10-kΩ load. |
