TP1561A-TR from UMW, 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, rail-to-rail swing with 100mA output capability and infinite short-circuit duration. |
| 2 | -Vs | power_in | Negative supply (ground in single-supply use); total supply (+Vs)-(-Vs) is 2.5V to 6V, 7V absolute maximum. |
| 3 | +In | input | Non-inverting input with rail-to-rail common-mode range extending 0.1V beyond each supply; input current limited to ±10mA. |
| 4 | -In | input | Inverting input with rail-to-rail common-mode range extending 0.1V beyond each supply; input current limited to ±10mA. |
| 5 | +Vs | power_in | Positive supply, 2.5V to 6V relative to -Vs, 7V absolute maximum. |
