SLS SL4558

SL4558
Dual Operational Amplifiers
The SL4558 is dual general purpose operational amplifiers.
The high common-mode input voltage range and the absence of
latch-up make these amplifiers ideal for voltage follower application.
The devices are short circuit protected and the internal frequency
compensation ensures stability without external components.

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range
GND≤(VIN or VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC).
Unused outputs must be left open.
