**XBLW** · Operational Amplifier · SOP-8

LM2904DTR from XBLW, in a SOP-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 | Output of amplifier 1. |
| 2 | In1- | input | Inverting input of amplifier 1; input common-mode range is -0.3 V to VCC. |
| 3 | In1+ | input | Non-inverting input of amplifier 1; input common-mode range is -0.3 V to VCC. |
| 4 | Vcc- | power_in | Negative supply (VEE/GND) for both amplifiers; common-mode range extends to this rail. |
| 5 | In2+ | input | Non-inverting input of amplifier 2; input common-mode range is -0.3 V to VCC. |
| 6 | In2- | input | Inverting input of amplifier 2; input common-mode range is -0.3 V to VCC. |
| 7 | Out2 | output | Output of amplifier 2. |
| 8 | Vcc+ | power_in | Positive supply for both amplifiers; 3V to 32V single supply (or ±1.5V to ±16V dual), absolute maximum 32 V. |
