# INA193AIDBVR

**Texas Instruments** · Current-Sensing Amplifiers · SOT-23-5

INA193AIDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Analog voltage output proportional to the sensed shunt current (Vout = Gain x Vsense, Gain = 20V/V for INA193). Swings from (VGND)+3mV up to (V+)-0.1V. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | VIN+ | input | Positive differential shunt-sense input. Connect to the shunt-resistor side that carries the higher potential. Common-mode range -16V to +80V, independent of supply. Input bias current typ +/-8 uA. |
| 4 | VIN- | input | Negative differential shunt-sense input. Connect to the load side of the shunt resistor. Common-mode range -16V to +80V; differential (VIN+ - VIN-) rated +/-18V. |
| 5 | V+ | power_in | Positive supply input. Operating range +2.7V to +18V. Quiescent current typ 700 uA (max 900 uA at 25C). |

## CAD (KiCad official)

- Symbol: `INA193AIDBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `ina193aidbvr-etched.step` / `ina193aidbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ina193aidbvr.step` / `ina193aidbvr.glb` are the bare package body.
