# SM73308MG

**Texas Instruments** · Operational Amplifier · SC-70-5

SM73308MG from Texas Instruments, 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; the common-mode input voltage range is 0 to V+ −0.9V, and the input current is limited to ±10 mA. |
| 2 | GND | power_in | Ground / negative supply (V−) connection; total supply V+ to V− must stay within 2.7V to 5.5V (absolute maximum 5.75V). |
| 3 | -IN | input | Inverting input; input pin voltage must stay between (V−) −0.3V and (V+) +0.3V, and input current is limited to ±10 mA. |
| 4 | VOUT | output | Rail-to-rail amplifier output (within 100 mV of rail at RL = 600Ω); shorting the output to V+ or V− will adversely affect reliability. |
| 5 | V+ | power_in | Positive supply connection; operating supply range is 2.7V to 5.5V, with an absolute maximum of 5.75V. |
