DESCRIPTION
The LS404 is a high performance quad operational
amplifier with frequency and phase compensation
built intothe chip. The internal phasecompensation
allows stable operation as voltage follower in spite
of its high Gain-Bandwidth Product.
The circuit presents very stable electrical characteristics over the entire supply voltage range, and
it particularly intended for professional and telecom
applications (active filters, 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.
