INA214CIRSWR

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

INA214CIRSWR 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; can be left floating or connected to any voltage between V- and V+.
2 IN+ input Positive input to shunt sense amplifier; connect to shunt resistor power-side terminal.
3 IN+ input Positive input to shunt sense amplifier; connect in parallel with pin 2.
4 IN- input Negative input to shunt sense amplifier; connect to shunt resistor load-side terminal.
5 IN- input Negative input to shunt sense amplifier; connect in parallel with pin 4.
6 V+ power_in Analog power supply, 2.7V to 26V.
7 NC unconnected No internal connection; can be left floating or connected to any voltage between V- and V+.
8 REF input Reference voltage input (0V to V+) that establishes the zero-current output baseline voltage.
9 GND power_in Analog ground reference.
10 OUT output Analog voltage output proportional to shunt current with 100 V/V gain; output swing (V+)−0.05 V to (V+)−0.2 V and (GND)+0.005 V to (GND)+0.05 V.
