INA283AQDRQ1

Texas Instruments · Current-Sensing Amplifiers · SOIC-8

INA283AQDRQ1 from Texas Instruments, in a SOIC-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 -IN input Connection to the negative side of the shunt resistor.
2 GND power_in Analog ground.
3 REF2 input Reference voltage input, 0 V to V+; see the Reference Pin Connection Options section for connection options.
4 NC unconnected Not internally connected; the pin should be left floating or connected to GND.
5 OUT output Analog output voltage.
6 V+ power_in Analog power supply, 2.7 V to 18 V.
7 REF1 input Reference voltage input, 0 V to V+; see the Reference Pin Connection Options section for connection options.
8 +IN input Connection to the positive side of the shunt resistor.
