**Texas Instruments** · Operational Amplifier · SOIC-8

OPA2822U 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 of amplifier A, which the datasheet rates for at least ±90mA min in linear operation at +25°C (sourcing +90mA min, sinking -90mA min). |
| 2 | -In A | input | Inverting input of amplifier A; differential input voltage is limited to ±1.2V absolute maximum and the input voltage range to ±VS. |
| 3 | +In A | input | Non-inverting input of amplifier A; common-mode input range is ±4.5V min at +25°C and the input voltage range is limited to ±VS. |
| 4 | -VS | power_in | Negative power supply; specified operating voltage is ±6V, maximum operating voltage is ±6.3V, and the absolute maximum supply is ±6.5V. |
| 5 | +In B | input | Non-inverting input of amplifier B; common-mode input range is ±4.5V min at +25°C and the input voltage range is limited to ±VS. |
| 6 | -In B | input | Inverting input of amplifier B; differential input voltage is limited to ±1.2V absolute maximum and the input voltage range to ±VS. |
| 7 | Out B | output | Output of amplifier B, which the datasheet rates for at least ±90mA min in linear operation at +25°C (sourcing +90mA min, sinking -90mA min). |
| 8 | +VS | power_in | Positive power supply; specified operating voltage is ±6V, maximum operating voltage is ±6.3V, and the absolute maximum supply is ±6.5V. |
