# INA185A1IDRLT

**Texas Instruments** · Current Sense Amplifiers · SOT-563

INA185A1IDRLT from Texas Instruments, in a SOT-563. 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 | OUT | output | Analog output voltage from the current-sense amplifier. |
| 2 | GND | power_in | Analog ground reference. |
| 3 | IN+ | input | Current-sense amplifier positive input; for high-side topologies connect to the bus-voltage side of the sense resistor, for low-side topologies connect to the load side. |
| 4 | IN- | input | Current-sense amplifier negative input; for high-side topologies connect to the load side of the sense resistor, for low-side topologies connect to the ground side. |
| 5 | REF | input | Reference voltage input for output voltage offset adjustment. |
| 6 | VS | power_in | Power supply input, rated 2.7 V to 5.5 V. |
