# TSV621ILT

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

TSV621ILT 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 | In+ | input | Non-inverting input with rail-to-rail common-mode range from (VCC-) - 0.1 V to (VCC+) + 0.1 V. |
| 2 | VDD | power_in | Negative supply / ground reference (VDD = 0 V in the electrical tables); labelled VDD on the TSV621 pinout, equivalent to VCC-. |
| 3 | In- | input | Inverting input with rail-to-rail common-mode range from (VCC-) - 0.1 V to (VCC+) + 0.1 V. |
| 4 | Out | output | Rail-to-rail output swinging within 35 mV max of the rails into 10 kOhm; unity-gain stable for capacitive loads up to 100 pF. |
| 5 | VCC | power_in | Positive supply, operating range 1.5 V to 5.5 V (absolute maximum 6 V); 10 nF decoupling capacitor recommended close to the pin. |

## CAD (KiCad official)

- Symbol: `TSV621ILT`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tsv621ilt-etched.step` / `tsv621ilt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tsv621ilt.step` / `tsv621ilt.glb` are the bare package body.
