INA199B1RSWR

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

INA199B1RSWR 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 connected to the power side of the shunt resistor; dual IN+ pins must be tied together; common mode input range -0.1V to 26V.
3 IN+ input Analog input connected to the power side of the shunt resistor; dual IN+ pins must be tied together; common mode input range -0.1V to 26V.
4 IN- input Analog input connected to the load side of the shunt resistor; dual IN- pins must be tied together; common mode input range -0.1V to 26V.
5 IN- input Analog input connected to the load side of the shunt resistor; dual IN- pins must be tied together; common mode input range -0.1V to 26V.
6 V+ power_in Analog power supply; operating voltage range 2.7V to 26V; sets the upper output range limit.
7 NC unconnected No internal connection; may be left floating or connected to any voltage between GND and V+.
8 REF input Reference voltage input; voltage range 0V to V+; sets the output offset voltage for single or bidirectional current measurement.
9 GND power_in Analog ground; reference point for all voltage measurements.
10 OUT output Analog output voltage; output swing limited to (V+)-0.05V to (V+)-0.2V relative to V+, and (GND)+0.005V to (GND)+0.05V relative to GND.
