INA211CIRSWR

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

INA211CIRSWR 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; the pin may be left floating or connected to any voltage between V- and V+.
2 IN+ input Analog input connected to the power-supply side of the shunt resistor; pins 2 and 3 must be tied together.
3 IN+ input Analog input connected to the power-supply side of the shunt resistor; pin 3 must be tied to pin 2.
4 IN- input Analog input connected to the load side of the shunt resistor; pins 4 and 5 must be tied together.
5 IN- input Analog input connected to the load side of the shunt resistor; pin 5 must be tied to pin 4.
6 V+ power_in Supply pin, 2.7 V to 26 V.
7 NC unconnected No internal connection; the pin may be left floating or connected to any voltage between V- and V+.
8 REF input Reference voltage input, 0 V to V+, which sets the output level at zero differential input; drive it from a buffered source when using a resistive divider.
9 GND power_in Analog ground.
10 OUT output Analog output voltage, whose swing is limited by the V+ supply pin voltage (absolute maximum GND - 0.3 V to (V+) + 0.3 V).
