OPA2227P from Texas Instruments, in a PDIP-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 of amplifier channel A. |
| 2 | -In A | input | Inverting input of channel A. |
| 3 | +In A | input | Non-inverting input of channel A. |
| 4 | V- | power_in | Negative (lowest) power supply; recommended dual supply is ±2.25 V to ±18 V (single supply 4.5 V to 36 V). |
| 5 | +In B | input | Non-inverting input of channel B. |
| 6 | -In B | input | Inverting input of channel B. |
| 7 | Out B | output | Output of amplifier channel B. |
| 8 | V+ | power_in | Positive (highest) power supply; see V- for the recommended supply range of ±2.25 V to ±18 V (single supply 4.5 V to 36 V). |
