# INA186A1IDCKT

**Texas Instruments** · Current Sense Amplifiers · SC-70-6

INA186A1IDCKT from Texas Instruments, in a SC-70-6. 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 | REF | input | Reference input that offsets OUT and enables bidirectional sensing when driven by an external voltage; the datasheet recommends a buffered reference and limits VREF to the GND to VS range. |
| 2 | GND | power_in | Analog ground for the device; the input common-mode range is specified as GND - 0.2 V to 40 V. |
| 3 | VS | power_in | Analog supply pin, specified for 1.7 V to 5.5 V operation. |
| 4 | IN+ | input | Positive current-sense amplifier input, connected to the bus-voltage side of the sense resistor for high-side sensing or the load side for low-side sensing; input pin voltage range is GND - 0.2 V to 40 V. |
| 5 | IN- | input | Negative current-sense amplifier input, connected to the load side of the sense resistor for high-side sensing or the ground side for low-side sensing; input pin voltage range is GND - 0.2 V to 40 V. |
| 6 | OUT | output | Analog output equal to the gain times the differential voltage (IN+ minus IN-) plus the voltage applied to REF; it swings to within 40 mV of VS and to within 1 mV of GND under specified load. |
