# INA186A4IDCKR

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

INA186A4IDCKR 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; external voltage applied to this pin offsets output for bidirectional current measurement. |
| 2 | GND | power_in | Analog ground reference. |
| 3 | VS | power_in | Power supply pin; rated voltage range 1.7V to 5.5V. |
| 4 | IN+ | input | Positive differential input; common-mode voltage range (GND−0.2V) to +40V; connect to sense resistor bus voltage side for high-side sensing or load side for low-side sensing. |
| 5 | IN- | input | Negative differential input; common-mode voltage range (GND−0.2V) to +40V; connect to sense resistor load side for high-side sensing or ground side for low-side sensing. |
| 6 | OUT | output | Analog output pin providing gain-amplified differential voltage; VOUT = GAIN × (IN+−IN−) + VREF, with output swing limited to (VS−40mV) maximum and (GND+1mV) minimum. |
