SL2122C

Slkor SLKORMICRO Elec · Operational Amplifier · SOP-8

SL2122C from Slkor SLKORMICRO Elec, 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 OUT1 output Output of amplifier 1, which swings to within 60 mV typ of either supply rail with a 10 kΩ load.
2 IN1- input Inverting input of amplifier 1; the common-mode input range extends 100 mV beyond the supply rails, from (V-) - 0.1 V to (V+) + 0.1 V.
3 IN1+ input Non-inverting input of amplifier 1; the common-mode input range extends 100 mV beyond the supply rails, from (V-) - 0.1 V to (V+) + 0.1 V.
4 V- power_in Negative supply or ground; the device operates with a supply span (V+) - (V-) of 3 V to 14 V.
5 IN2+ input Non-inverting input of amplifier 2; the common-mode input range extends 100 mV beyond the supply rails, from (V-) - 0.1 V to (V+) + 0.1 V.
6 IN2- input Inverting input of amplifier 2; the common-mode input range extends 100 mV beyond the supply rails, from (V-) - 0.1 V to (V+) + 0.1 V.
7 OUT2 output Output of amplifier 2, which swings to within 60 mV typ of either supply rail with a 10 kΩ load.
8 V+ power_in Positive supply; the device operates with a supply span (V+) - (V-) of 3 V to 14V, with an absolute maximum of 18 V.
