LM2904XK-G from Jiangsu RUNIC Tech, 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 | OUTA | output | Output of channel A; the output swings between the supply rails, and the datasheet limits output pins to (V-) - 0.3 V to (V+) + 0.3 V. |
| 2 | -INA | input | Inverting input of channel A; the datasheet limits signal input pins to (V-) - 0.3 V to (V+) + 0.3 V. |
| 3 | +INA | input | Noninverting input of channel A; the input common-mode range is (V-) to (V+) - 1.5 V (V+) - 2 V across temperature. |
| 4 | V- | power_in | Negative (lowest) power supply or ground, used for single-supply operation. |
| 5 | +INB | input | Noninverting input of channel B; the input common-mode range is (V-) to (V+) - 1.5 V (V+) - 2 V across temperature. |
| 6 | -INB | input | Inverting input of channel B; the datasheet limits signal input pins to (V-) - 0.3 V to (V+) + 0.3 V. |
| 7 | OUTB | output | Output of channel B; the output swings between the supply rails, and the datasheet limits output pins to (V-) - 0.3 V to (V+) + 0.3 V. |
| 8 | V+ | power_in | Positive (highest) power supply; the operating supply range is 3 V to 36 V single-supply or ±1.5 V to ±18 V dual-supply. |
