LM258AM

HGSEMI · Operational Amplifier · SOP-8

LM258AM from HGSEMI, 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 op-amp channel 1.
2 1IN- input Inverting input of op-amp channel 1.
3 1IN+ input Non-inverting input of op-amp channel 1.
4 VEE power_in Negative power supply; datasheet specifies VEE = GND for single-supply operation (single supply 3 V to 36 V, dual supply ±18 V).
5 2IN+ input Non-inverting input of op-amp channel 2.
6 2IN- input Inverting input of op-amp channel 2.
7 2OUT output Output of op-amp channel 2.
8 VCC power_in Positive power supply; datasheet gives single-supply range 3 V to 36 V and absolute maximum single supply of 36 V.
