INA2290A3IDGKR

Texas Instruments · Current Sense Amplifiers · VSSOP-8

INA2290A3IDGKR from Texas Instruments, in a VSSOP-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+1 input Current-sense amplifier positive input for channel 1; connect to the bus-voltage side of the channel 1 sense resistor.
2 IN-1 input Current-sense amplifier negative input for channel 1; connect to the load side of the channel 1 sense resistor.
3 IN+2 input Current-sense amplifier positive input for channel 2; connect to the bus-voltage side of the channel 2 sense resistor.
4 IN-2 input Current-sense amplifier negative input for channel 2; connect to the load side of the channel 2 sense resistor.
5 GND power_in Ground reference pin for the device.
6 OUT2 output Channel 2 output voltage.
7 OUT1 output Channel 1 output voltage.
8 VS power_in Power supply input; the recommended operating supply range is 2.7 V to 20 V.
