LM258AN

HGSEMI · Operational Amplifier · DIP-8

LM258AN from HGSEMI, in a DIP-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, which the datasheet describes as the channel 1 amplifier output.
2 1IN- input Inverting input of op-amp channel 1; the datasheet limits the input common-mode voltage (VICR) to -0.3 V to 36 V.
3 1IN+ input Non-inverting input of op-amp channel 1; the datasheet limits the input common-mode voltage (VICR) to -0.3 V to 36 V.
4 VEE power_in Negative power supply; in single-supply operation it is tied to GND (VEE = 0 V).
5 2IN+ input Non-inverting input of op-amp channel 2; the datasheet limits the input common-mode voltage (VICR) to -0.3 V to 36 V.
6 2IN- input Inverting input of op-amp channel 2; the datasheet limits the input common-mode voltage (VICR) to -0.3 V to 36 V.
7 2OUT output Output of op-amp channel 2, which the datasheet describes as the channel 2 amplifier output.
8 VCC power_in Positive power supply; the datasheet gives a single-supply range of 3 V to 36 V, a dual-supply range of ±18 V, and an absolute maximum of 36 V.
