Texas Instruments · Current Sense Amplifiers · VSSOP-10-0.5mm
INA2181A1IDGSR from Texas Instruments, in a VSSOP-10-0.5mm. 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 proportional to measured current across sense resistor. |
| 2 | IN-1 | input | Channel 1 current sense amplifier negative input; connect to load side for high-side sensing or to ground side for low-side sensing configuration. |
| 3 | IN+1 | input | Channel 1 current sense amplifier positive input; connect to bus voltage side for high-side sensing or to load side for low-side sensing configuration. |
| 4 | GND | power_in | Analog ground reference for the differential measurement circuit. |
| 5 | REF1 | input | Channel 1 reference input for setting output baseline voltage, operating range 0V to VS. |
| 6 | REF2 | input | Channel 2 reference input for setting output baseline voltage, operating range 0V to VS. |
| 7 | IN+2 | input | Channel 2 current sense amplifier positive input; connect to bus voltage side for high-side sensing or to load side for low-side sensing configuration. |
| 8 | IN-2 | input | Channel 2 current sense amplifier negative input; connect to load side for high-side sensing or to ground side for low-side sensing configuration. |
| 9 | OUT2 | output | Channel 2 analog output voltage proportional to measured current across sense resistor. |
| 10 | VS | power_in | Analog power supply input pin, operating range 2.7V to 5.5V. |
