INA199B1DCKR from Texas Instruments, in a SC-70-6. 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 offset (typically tied to GND for unidirectional or to Vref/2 for bidirectional current sensing).
2	GND	power_in	Device ground reference.
3	V+	power_in	Positive power supply, 2.7 V to 26 V. Bypass to GND with 0.01 µF to 0.1 µF ceramic capacitor.
4	IN+	input	Analog input, connects to the supply side of the shunt resistor. Common-mode range -0.3 V to 26 V (independent of V+).
5	IN-	input	Analog input, connects to the load side of the shunt resistor. Common-mode range -0.3 V to 26 V (independent of V+).
6	OUT	output	Analog voltage output. Output = Gain × (V(IN+) − V(IN−)) + V(REF); gain is 50 V/V for the B1 version.
