LM2904M from HGSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Op-amp 1 output. Push-pull output with short-circuit protection; typical short-circuit current ±24 mA. Output swing on a 15 V single supply: VOH ~13.6 V (Iout=-50µA), VOL ~0.1 V (Iout=50µA). |
| 2 | 1IN- | input | Op-amp 1 inverting input. Common-mode input range VEE to VCC-1.5V; typical input bias current 50 nA and offset current 10 nA at VO=1.4 V. |
| 3 | 1IN+ | input | Op-amp 1 non-inverting input. Common-mode input range VEE to VCC-1.5V; ±36 V max differential input voltage between IN+ and IN-. |
| 4 | VEE | power_in | Negative supply / ground. Tie to GND for single-supply operation (3V-36V VCC) or to a negative rail for split-supply operation up to ±18 V. |
| 5 | 2IN+ | input | Op-amp 2 non-inverting input. Same electrical characteristics as 1IN+: common-mode range VEE to VCC-1.5V, ±36 V differential limit. |
| 6 | 2IN- | input | Op-amp 2 inverting input. Typical input bias current 50 nA, offset current 10 nA at VO=1.4 V. |
| 7 | 2OUT | output | Op-amp 2 output. Push-pull output with short-circuit protection; typical short-circuit current ±24 mA. Same output swing characteristics as 1OUT. |
| 8 | VCC | power_in | Positive supply. Single-supply range 3V-36V (VEE=GND) or ±18 V split supply. Typical quiescent current 0.5 mA @ VCC=5V, 0.8 mA @ VCC=36V (no load). |
