DESCRIPTION
The LS404 is a high performance quad operation-
al amplifier with frequency and phase compensa-
tion built into the chip. The internal phase compen-
sation allows stable operation as voltage follower
in spite of its high Gain-Bandwidth Product.
The circuit presents very stable electrical charac-
teristics over the entire supply voltage range, and
is particularly intended for professional and tele-
com applications (active filter, etc).
The patented input stage circuit allows small input
signal swings below the negative supply voltage
and prevents phase inversion when the inputs are
over drivers.
