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.
