INA199B2DCKR

Texas Instruments · Current-Sensing Amplifiers · SOT-363-6

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.
