INA4180A4QPWRQ1

Texas Instruments · Current Sense Amplifiers · TSSOP-14

INA4180A4QPWRQ1 from Texas Instruments, in a TSSOP-14. 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 OUT1 output Channel 1 analog output voltage of the current-sense amplifier, swinging between GND and VS as limited by the rail-to-rail output specifications.
2 IN-1 input Channel 1 current-sense amplifier negative input; connect to the load side of the sense resistor for high-side sensing or to the ground side for low-side sensing.
3 IN+1 input Channel 1 current-sense amplifier positive input; connect to the bus-voltage side of the sense resistor for high-side sensing or to the load side for low-side sensing, with a common-mode range of -0.2 V to +26 V.
4 VS power_in Power supply pin, operating range 2.7 V to 5.5 V, which should be bypassed with at least 0.1 µF close to the device.
5 IN+2 input Channel 2 current-sense amplifier positive input; connect to the bus-voltage side of the sense resistor for high-side sensing or to the load side for low-side sensing.
6 IN-2 input Channel 2 current-sense amplifier negative input; connect to the load side of the sense resistor for high-side sensing or to the ground side for low-side sensing.
7 OUT2 output Channel 2 analog output voltage of the current-sense amplifier, swinging between GND and VS as limited by the rail-to-rail output specifications.
8 OUT3 output Channel 3 analog output voltage of the current-sense amplifier, swinging between GND and VS as limited by the rail-to-rail output specifications.
9 IN-3 input Channel 3 current-sense amplifier negative input; connect to the load side of the sense resistor for high-side sensing or to the ground side for low-side sensing.
10 IN+3 input Channel 3 current-sense amplifier positive input; connect to the bus-voltage side of the sense resistor for high-side sensing or to the load side for low-side sensing.
11 GND power_in Analog ground reference for the device; connect the ADC reference or microcontroller ground as close to this pin as possible.
12 IN+4 input Channel 4 current-sense amplifier positive input; connect to the bus-voltage side of the sense resistor for high-side sensing or to the load side for low-side sensing.
13 IN-4 input Channel 4 current-sense amplifier negative input; connect to the load side of the sense resistor for high-side sensing or to the ground side for low-side sensing.
14 OUT4 output Channel 4 analog output voltage of the current-sense amplifier, swinging between GND and VS as limited by the rail-to-rail output specifications.
