OA1ZHA22C 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 of (VCC-) - 0.1 V to (VCC+) + 0.1 V, with input current limited to 10 mA by a series resistor. |
| 2 | VCC- | power_in | Negative supply voltage (ground in single-supply use); supply range VCC is 1.8 V to 5.5 V. |
| 3 | IN- | input | Inverting input; rail-to-rail common-mode range of (VCC-) - 0.1 V to (VCC+) + 0.1 V, with input current limited to 10 mA by a series resistor. |
| 4 | OUT | output | Rail-to-rail amplifier output swinging to within 30 mV of either rail at 25 °C with a 10 kΩ load to VCC/2. |
| 5 | VCC+ | power_in | Positive supply voltage of 1.8 V to 5.5 V (6 V absolute maximum); a 0.1 µF decoupling capacitor close to the supply pins is recommended. |
