OPA2211AIDDAR from Texas Instruments, in a SOIC-8-EP. 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 channel A; delivers 30mA sourcing or 45mA sinking maximum current with output swing (V-) + 0.6V to (V+) - 0.6V. |
| 2 | -IN A | input | Inverting input channel A; accepts voltages from (V-) - 0.5V to (V+) + 0.5V absolute maximum with input bias current ±175nA max. |
| 3 | +IN A | input | Noninverting input channel A; accepts voltages from (V-) - 0.5V to (V+) + 0.5V absolute maximum with input bias current ±175nA max. |
| 4 | V- | power_in | Negative power supply; operates 4.5V to 36V single supply (±2.25V to ±18V dual supply) with absolute maximum 40V supply voltage difference. |
| 5 | +IN B | input | Noninverting input channel B; accepts voltages from (V-) - 0.5V to (V+) + 0.5V absolute maximum with input bias current ±175nA max. |
| 6 | -IN B | input | Inverting input channel B; accepts voltages from (V-) - 0.5V to (V+) + 0.5V absolute maximum with input bias current ±175nA max. |
| 7 | OUT B | output | Output channel B; delivers 30mA sourcing or 45mA sinking maximum current with output swing (V-) + 0.6V to (V+) - 0.6V. |
| 8 | V+ | power_in | Positive power supply; operates 4.5V to 36V single supply (±2.25V to ±18V dual supply) with absolute maximum 40V supply voltage difference. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
