INA199C3RSWR

Texas Instruments · Current Sense Amplifiers · UQFN-10(1.4x1.8)

INA199C3RSWR 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; may be left floating or connected to any voltage between GND and V+.
2 IN+ input Analog input; connect to power supply side of shunt resistor; must be tied together with pin 3.
3 IN+ input Analog input; connect to power supply side of shunt resistor; must be tied together with pin 2.
4 IN- input Analog input; connect to load side of shunt resistor; must be tied together with pin 5.
5 IN- input Analog input; connect to load side of shunt resistor; must be tied together with pin 4.
6 V+ power_in Analog power supply, 2.7V to 26V.
7 NC unconnected No internal connection; may be left floating or connected to any voltage between GND and V+.
8 REF input Analog reference input voltage, 0V to V+; sets output offset for single-ended or bidirectional operation.
9 GND power_in Analog ground; return path for signal and power circuits.
10 OUT output Analog output; 200V/V gain with output swing from GND+5mV to V+-50mV into 10kΩ load.
