OPA2211AIDDA from Texas Instruments, in a SOP-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 with voltage swing from (V-) + 0.2V to (V+) - 0.2V at RL = 10kΩ and maximum output current capability of 30mA source or 45mA sink. |
| 2 | -IN A | input | Inverting input channel A with common-mode voltage range from (V-) + 1.8V to (V+) - 1.4V for dual supply voltages ≥ ±5V. |
| 3 | +IN A | input | Non-inverting input channel A with common-mode voltage range from (V-) + 1.8V to (V+) - 1.4V for dual supply voltages ≥ ±5V. |
| 4 | V- | power_in | Negative power supply rail with rated supply voltage range ±2.25V to ±18V (dual supply) or 4.5V to 36V (single supply). |
| 5 | +IN B | input | Non-inverting input channel B with common-mode voltage range from (V-) + 1.8V to (V+) - 1.4V for dual supply voltages ≥ ±5V. |
| 6 | -IN B | input | Inverting input channel B with common-mode voltage range from (V-) + 1.8V to (V+) - 1.4V for dual supply voltages ≥ ±5V. |
| 7 | OUT B | output | Output channel B with voltage swing from (V-) + 0.2V to (V+) - 0.2V at RL = 10kΩ and maximum output current capability of 30mA source or 45mA sink. |
| 8 | V+ | power_in | Positive power supply rail with rated supply voltage range ±2.25V to ±18V (dual supply) or 4.5V to 36V (single supply). |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
