# TS1851ILT

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

TS1851ILT 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 | Amplifier output with rail-to-rail swing, able to drive 500 pF load and sourcing/sinking about 48 mA maximum short-circuit current. |
| 2 | VCC- | power_in | Negative supply (ground) terminal; supply range VCC is 1.8 to 6 V between VCC+ and VCC-. |
| 3 | In+ | input | Non-inverting input with rail-to-rail common-mode range of VCC- - 0.2 V to VCC+ + 0.2 V; differential input limited to ±1 V. |
| 4 | In- | input | Inverting input with rail-to-rail common-mode range of VCC- - 0.2 V to VCC+ + 0.2 V; differential input limited to ±1 V. |
| 5 | VCC+ | power_in | Positive supply terminal, operating from 1.8 to 6 V above VCC- (absolute maximum 7 V). |
