LM258DR-CN

ChipNobo · Operational Amplifier · SOP-8

LM258DR-CN from ChipNobo, 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 amplifier 1; the datasheet gives typical source current of 40 mA and sink current of 15 mA at VCC = 15 V, Vo = 2 V.
2 1IN- input Inverting input of amplifier 1, with the input common-mode voltage kept within the -0.3 V to VCC limits of the maximum ratings.
3 1IN+ input Non-inverting input of amplifier 1, with the input common-mode voltage kept within the -0.3 V to VCC limits of the maximum ratings.
4 GND power_in Ground reference, labelled VEE/GND in the schematic, serving as the negative supply in split-supply operation.
5 2IN+ input Non-inverting input of amplifier 2, with the input common-mode voltage kept within the -0.3 V to VCC limits of the maximum ratings.
6 2IN- input Inverting input of amplifier 2, with the input common-mode voltage kept within the -0.3 V to VCC limits of the maximum ratings.
7 2OUT output Output of amplifier 2; the datasheet gives typical source current of 40 mA and sink current of 15 mA at VCC = 15 V, Vo = 2 V.
8 VCC power_in Positive supply, rated 4 V to 32 V single-supply or ±2 V to ±16 V dual-supply, with a maximum of 32 V (or ±16 V).
