Slkor SLKORMICRO Elec · Operational Amplifier · SOP-8
LM2904 from Slkor SLKORMICRO Elec, 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 op-amp A; the datasheet permits continuous short-circuit to ground for one amplifier when VCC is 15 V or less at Ta = 25 °C. |
| 2 | INAN | input | Inverting input of op-amp A; the common-mode input range is 0 to VCC−1.5 V, the absolute input voltage is limited to −0.3 V to 24 V, and input current is limited to 50 mA when VIN is below −0.3 V. |
| 3 | INAP | input | Non-inverting input of op-amp A; the common-mode input range is 0 to VCC−1.5 V, the absolute input voltage is limited to −0.3 V to 24 V, and input current is limited to 50 mA when VIN is below −0.3 V. |
| 4 | GND | power_in | Negative power supply pin, used for both single-supply and dual-supply (±1.5 V to ±10 V) operation. |
| 5 | INBP | input | Non-inverting input of op-amp B; the common-mode input range is 0 to VCC−1.5 V, the absolute input voltage is limited to −0.3 V to 24 V, and input current is limited to 50 mA when VIN is below −0.3 V. |
| 6 | INBN | input | Inverting input of op-amp B; the common-mode input range is 0 to VCC−1.5 V, the absolute input voltage is limited to −0.3 V to 24 V, and input current is limited to 50 mA when VIN is below −0.3 V. |
| 7 | OUTB | output | Output of op-amp B; the datasheet permits continuous short-circuit to ground for one amplifier when VCC is 15 V or less at Ta = 25 °C. |
| 8 | VCC | power_in | Positive power supply pin; the datasheet gives a recommended single supply of 3 V to 20 V and an absolute maximum of 24 V (or ±12 V dual supply). |
