OPA843ID 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 | NC | unconnected | No connection; the datasheet marks this pin as NC (no connection). |
| 2 | Inverting Input | input | Inverting input of the op amp; the differential input voltage is limited to ±1.2V absolute maximum. |
| 3 | Noninverting Input | input | Noninverting input of the op amp; common-mode input range is ±3.2V min at 25°C with VS = ±5V. |
| 4 | -VS | power_in | Negative power supply; specified at −5V with a minimum operating voltage of ±4V and maximum operating voltage of ±6V (absolute maximum supply ±6.5V). |
| 5 | NC | unconnected | No connection; the datasheet marks this pin as NC (no connection). |
| 6 | Output | output | Output of the amplifier; output current is ±100mA min at VO = 0V (25°C). |
| 7 | +VS | power_in | Positive power supply; specified at +5V with a minimum operating voltage of ±4V and maximum operating voltage of ±6V (absolute maximum supply ±6.5V). |
| 8 | NC | unconnected | No connection; the datasheet marks this pin as NC (no connection). |
