LM2904XS8G

SGMICRO · Operational Amplifier · SOIC-8

LM2904XS8G from SGMICRO, in a SOIC-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 OUTA output Output of amplifier A; the output swing is limited to VOL of 190mV max and VOH of 60mV typ at RL = 10kΩ.
2 -INA input Inverting input of amplifier A; the common mode input range is -0.1V to VS - 1.5V, and if either input is below -0.3V its input current should be limited to 1mA.
3 +INA input Non-inverting input of amplifier A; the common mode input range is -0.1V to VS - 1.5V, and inputs may exceed VS up to the maximum VS without damage.
4 -VS power_in Negative supply rail, which is ground in single-supply operation; the valid supply span is 3V to 32V, or ±1.5V to ±16V for dual supplies.
5 +INB input Non-inverting input of amplifier B; the common mode input range is -0.1V to VS - 1.5V, and inputs may exceed VS up to the maximum VS without damage.
6 -INB input Inverting input of amplifier B; the common mode input range is -0.1V to VS - 1.5V, and if either input is below -0.3V its input current should be limited to 1mA.
7 OUTB output Output of amplifier B; the output swing is limited to VOL of 190mV max and VOH of 60mV typ at RL = 10kΩ.
8 +VS power_in Positive supply rail; the operating voltage range is 3V to 32V, with absolute maximum supply voltage of 34V.
