# XL2904D

**XINLUDA** · Operational Amplifier · SOP-8

XL2904D from XINLUDA, 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 | Output A | output | Amplifier A output, short-circuit protected, with a voltage range that includes the negative supply. |
| 2 | Input A- | input | Amplifier A inverting input, with a common mode range of -0.3 V to 32 V that includes the negative supply. |
| 3 | Input A+ | input | Amplifier A non-inverting input, with a common mode range of -0.3 V to 32 V that includes the negative supply. |
| 4 | VEE/GND | power_in | Negative supply or ground for single supply operation, or the negative rail for split supplies up to 16 V. |
| 5 | Input B+ | input | Amplifier B non-inverting input, with a common mode range of -0.3 V to 32 V that includes the negative supply. |
| 6 | Input B- | input | Amplifier B inverting input, with a common mode range of -0.3 V to 32 V that includes the negative supply. |
| 7 | Output B | output | Amplifier B output, short-circuit protected, with a voltage range that includes the negative supply. |
| 8 | VCC | power_in | Positive supply, 3.0 V to 32 V for single supply operation (absolute maximum 32 V), or up to 16 V for split supplies. |
