INA199A1RSWT

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

INA199A1RSWT 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 between GND and V+.
2 IN+ input Analog input connected to the power supply side of the shunt resistor.
3 IN+ input Analog input connected to the power supply side of the shunt resistor.
4 IN- input Analog input connected to the load side of the shunt resistor.
5 IN- input Analog input connected to the load side of the shunt resistor.
6 V+ power_in Power supply input, rated 2.7V to 26V.
7 NC unconnected No internal connection; may be left floating or connected between GND and V+.
8 REF input Analog input for reference voltage, 0V to V+.
9 GND power_in Analog ground.
10 OUT output Analog output voltage.
