# LM358DMR2G

**onsemi** · Operational Amplifier · MSOP-8

LM358DMR2G from onsemi, in a MSOP-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 | Output A | output | Output of amplifier A; the output voltage range includes the negative supply, and the output is short-circuit protected (short circuits to VCC can cause excessive heating and destruction). |
| 2 | Inputs A- | input | Inverting input of amplifier A; the common mode input range extends to VEE/ground and must not be taken more than 0.3 V below the negative supply. |
| 3 | Inputs A+ | input | Non-inverting input of amplifier A; the common mode input range extends to VEE/ground and must not be taken more than 0.3 V below the negative supply, with an upper limit of VCC − 1.7 V. |
| 4 | VEE/Gnd | power_in | Negative supply or ground for single-supply operation; the input common mode and output voltage ranges extend to this pin. |
| 5 | Inputs B+ | input | Non-inverting input of amplifier B; the common mode input range extends to VEE/ground and must not be taken more than 0.3 V below the negative supply, with an upper limit of VCC − 1.7 V. |
| 6 | Inputs B- | input | Inverting input of amplifier B; the common mode input range extends to VEE/ground and must not be taken more than 0.3 V below the negative supply. |
| 7 | Output B | output | Output of amplifier B; the output voltage range includes the negative supply, and the output is short-circuit protected (short circuits to VCC can cause excessive heating and destruction). |
| 8 | VCC | power_in | Positive supply; single-supply operation from 3.0 V to 32 V (absolute maximum 32 Vdc). |
