# TSX921ILT

**STMicroelectronics** · Operational Amplifier · SOT-23-5

TSX921ILT from STMicroelectronics, in a SOT-23-5. 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 | OUT | output | Rail-to-rail amplifier output, able to source 74 mA and sink 50 mA typ at VCC = 16 V. |
| 2 | VCC- | power_in | Negative supply, ground for single-supply operation; supply range 4 V to 16 V between VCC+ and VCC-. |
| 3 | IN+ | input | Non-inverting input, rail-to-rail with common mode range from (VCC-) - 0.1 V to (VCC+) + 0.1 V, input current limited to 10 mA. |
| 4 | IN- | input | Inverting input, rail-to-rail with common mode range from (VCC-) - 0.1 V to (VCC+) + 0.1 V, input current limited to 10 mA. |
| 5 | VCC+ | power_in | Positive supply, 4 V to 16 V operating range with 18 V absolute maximum. |

## CAD (KiCad official)

- Symbol: `TSX921ILT`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tsx921ilt-etched.step` / `tsx921ilt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tsx921ilt.step` / `tsx921ilt.glb` are the bare package body.
