About this IC
4558D is a dual operational amplifier.
Excellent channel separation allows the use of a dual
device in a single amp application. The SE/SA/NE4558 is a pin-for-pin replacement for the
RV/RM/RC4558.

# 2MHz unity-gain bandwidth 
# voltage ±18V for NE4558 and ±22V for SE4558
# It also Short-circuit protection.
#No frequency compensation required
#Large common-mode and differential voltage ranges
#Low power consumption.
