LM2904

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).
