OPA705PA 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 | NC | unconnected | Not connected; the datasheet DIP-8 pin diagram marks this pin NC. |
| 2 | -In | input | Inverting input; signals more than 0.3V beyond the supply rails must be current-limited to 10mA or less, and the common-mode range is (V-) - 0.3V to (V+) + 0.3V. |
| 3 | +In | input | Non-inverting input with rail-to-rail common-mode range of (V-) - 0.3V to (V+) + 0.3V, with input currents limited to 10mA when driven beyond the rails. |
| 4 | V- | power_in | Negative power supply; the device operates from a single supply of 4V to 12V or dual supplies of ±2V to ±6V, and the absolute maximum V+ to V- is 13.2V. |
| 5 | NC | unconnected | Not connected; the datasheet DIP-8 pin diagram marks this pin NC. |
| 6 | Out | output | Rail-to-rail output that swings to within 40mV of the rail at light loads and within 75mV with a 20kΩ load, with continuous short-circuit protection to ground (one amplifier per package). |
| 7 | V+ | power_in | Positive power supply; the specified single-supply range is 4V to 12V and the absolute maximum V+ to V- is 13.2V. |
| 8 | NC | unconnected | Not connected; the datasheet DIP-8 pin diagram marks this pin NC. |
