LM2904VQDRG4 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 | OUT1 | output | First operational amplifier output. |
| 2 | IN1- | input | First operational amplifier inverting input; common-mode input range V- to (V+ - 2V). |
| 3 | IN1+ | input | First operational amplifier non-inverting input; common-mode input range V- to (V+ - 2V). |
| 4 | V- | power_in | Negative power supply or ground reference for single-supply operation; total supply voltage range 3V to 30V. |
| 5 | IN2+ | input | Second operational amplifier non-inverting input; common-mode input range V- to (V+ - 2V). |
| 6 | IN2- | input | Second operational amplifier inverting input; common-mode input range V- to (V+ - 2V). |
| 7 | OUT2 | output | Second operational amplifier output. |
| 8 | V+ | power_in | Positive power supply; supply voltage range 3V to 30V above V-. |
