OPA2228UA from Texas Instruments, in a SOIC-8. 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 A | output | Output for channel A; maximum short-circuit current ±45 mA. |
| 2 | -In A | input | Inverting input for channel A; input signal voltage (V-) - 0.7 to (V+) + 0.7 V, maximum input current 20 mA. |
| 3 | +In A | input | Non-inverting input for channel A; input signal voltage (V-) - 0.7 to (V+) + 0.7 V, maximum input current 20 mA, common-mode voltage (V-) + 2 to (V+) - 2 V. |
| 4 | V- | power_in | Negative power supply (lowest); dual supply voltage ±2.25 to ±18 V or single supply 4.5 to 36 V. |
| 5 | +In B | input | Non-inverting input for channel B; input signal voltage (V-) - 0.7 to (V+) + 0.7 V, maximum input current 20 mA, common-mode voltage (V-) + 2 to (V+) - 2 V. |
| 6 | -In B | input | Inverting input for channel B; input signal voltage (V-) - 0.7 to (V+) + 0.7 V, maximum input current 20 mA. |
| 7 | Out B | output | Output for channel B; maximum short-circuit current ±45 mA. |
| 8 | V+ | power_in | Positive power supply (highest); dual supply voltage ±2.25 to ±18 V or single supply 4.5 to 36 V. |
