LM258A

Slkor SLKORMICRO Elec · Operational Amplifier · SOP-8

LM258A 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 1OUT output Output of operational amplifier 1; the electrical table gives source current of 20 mA min (40 mA typ) and sink current of 10 mA min (15 mA typ) at Vcc=15V, Vo=2V.
2 1IN- input Inverting input of operational amplifier 1; input voltage range is -0.3 V to VCC per the absolute maximum ratings.
3 1IN+ input Non-inverting input of operational amplifier 1; input common-mode range is 0 to Vcc-1.5 V per the electrical table.
4 GND power_in Ground pin, used as the negative supply (VEE) in dual-supply operation; the device can run from a single supply or from dual supplies.
5 2IN+ input Non-inverting input of operational amplifier 2; input common-mode range is 0 to Vcc-1.5 V per the electrical table.
6 2IN- input Inverting input of operational amplifier 2; input voltage range is -0.3 V to VCC per the absolute maximum ratings.
7 2OUT output Output of operational amplifier 2; the electrical table gives source current of 20 mA min (40 mA typ) and sink current of 10 mA min (15 mA typ) at Vcc=15V, Vo=2V.
8 VCC power_in Positive supply pin; absolute maximum supply voltage is 32 V (or ±16 V for dual supply).
