**STMicroelectronics** · Precision Op Amps · SC-70-5

TSU111ICT from STMicroelectronics, in a SC-70-5. 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 | IN+ | input | Non-inverting input; rail-to-rail common-mode range (VCC−) − 0.1 V to (VCC+) + 0.1 V; input bias current 10 pA max at 25 °C, input current must be limited to 10 mA max. |
| 2 | VCC- | power_in | Negative supply / ground reference; supply voltage range 1.5 V to 5.5 V, absolute maximum supply voltage 6 V. |
| 3 | IN- | input | Inverting input; rail-to-rail common-mode range (VCC−) − 0.1 V to (VCC+) + 0.1 V; input bias current 10 pA max at 25 °C, input current must be limited to 10 mA max. |
| 4 | OUT | output | Rail-to-rail output; VOH drop from VCC+ 25 mV max and VOL 25 mV max at RL = 10 kΩ, 25 °C; output sink/source current up to 45 mA / 41 mA at VCC+ = 5 V. |
| 5 | VCC+ | power_in | Positive supply; operating range 1.5 V to 5.5 V, absolute maximum 6 V; quiescent current 900 nA typ / 1200 nA max per channel at 25 °C. |

## CAD (KiCad official)

- Symbol: `TSU111ICT`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `tsu111ict-etched.step` / `tsu111ict-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tsu111ict.step` / `tsu111ict.glb` are the bare package body.
