SGM8273-1AXN5G from SGMICRO, 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, within 60mV (typ) of the rails at VS = ±18V with RL = 10kΩ and short-circuit protected (±40mA typ). |
| 2 | -VS | power_in | Negative supply; total supply +VS to -VS is 3.3V to 36V operating (40V absolute maximum), or ground in single-supply use. |
| 3 | +IN | input | Non-inverting input with rail-to-rail common-mode range of (-VS) - 0.1V to (+VS) + 0.1V. |
| 4 | -IN | input | Inverting input with rail-to-rail common-mode range of (-VS) - 0.1V to (+VS) + 0.1V. |
| 5 | +VS | power_in | Positive supply; total supply +VS to -VS is 3.3V to 36V operating (40V absolute maximum). |
