OPA2145IDR 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, can swing from (V-) + 0.1 V to (V+) - 0.1 V with 10 kΩ load and supports ±20 mA short-circuit current. |
| 2 | -IN A | input | Inverting input for channel A, accepts common-mode voltage from (V-) - 0.1 V to (V+) - 3.5 V with maximum input current ±10 mA. |
| 3 | +IN A | input | Noninverting input for channel A, accepts common-mode voltage from (V-) - 0.1 V to (V+) - 3.5 V with maximum input current ±10 mA. |
| 4 | V- | power_in | Negative supply voltage with absolute maximum rating of ±20 V for dual supply or 40 V for single supply operation. |
| 5 | +IN B | input | Noninverting input for channel B, accepts common-mode voltage from (V-) - 0.1 V to (V+) - 3.5 V with maximum input current ±10 mA. |
| 6 | -IN B | input | Inverting input for channel B, accepts common-mode voltage from (V-) - 0.1 V to (V+) - 3.5 V with maximum input current ±10 mA. |
| 7 | OUT B | output | Output for channel B, can swing from (V-) + 0.1 V to (V+) - 0.1 V with 10 kΩ load and supports ±20 mA short-circuit current. |
| 8 | V+ | power_in | Positive supply voltage with absolute maximum rating of ±20 V for dual supply or 40 V for single supply operation. |
