# INA202AIDGKR

**Texas Instruments** · Current Sense Amplifiers · VSSOP-8

INA202AIDGKR 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 | VS | power_in | Power supply pin; the datasheet gives a recommended operating supply of 2.7 V to 18 V (12 V nominal). |
| 2 | OUT | output | Analog output voltage of the current-shunt monitor; absolute maximum range is GND - 0.3 V to (VS) + 0.3 V. |
| 3 | CMPIN | input | Comparator input; absolute maximum range is GND - 0.3 V to (VS) + 0.3 V. |
| 4 | GND | power_in | Analog ground reference for the device. |
| 5 | RESET | input | Active-low comparator reset; grounding or leaving it open makes the comparator transparent, and its absolute maximum range is GND - 0.3 V to (VS) + 0.3 V. |
| 6 | CMPOUT | output | Open-drain comparator output; the absolute maximum rating for the comparator output is GND - 0.3 V to 18 V. |
| 7 | VIN- | power_in | Connect to the low side of the shunt resistor, using Kelvin connections; common-mode range is -16 V to 80 V. |
| 8 | VIN+ | power_in | Connect to the high side of the shunt resistor, using Kelvin connections; common-mode range is -16 V to 80 V. |
